+_Have something you'd like to contribute to the framework?  We welcome pull
+requests, but ask that you carefully read this document first to understand how
+best to submit them; what kind of changes are likely to be accepted; and what
+to expect from the Spring team when evaluating your submission._
+
+_Please refer back to this document as a checklist before issuing any pull
+request; this will save time for everyone!_
+
+## Understand the basics
+
+Not sure what a pull request is, or how to submit one?  Take a look at GitHub's
+excellent [help documentation][] first.
+
+
+## Search JIRA first; create an issue if necessary
+
+Is there already an issue that addresses your concern?  Do a bit of searching
+in our [JIRA issue tracker][] to see if you can find something similar. If not,
+please create a new issue before submitting a pull request unless the change is
+truly trivial, e.g. typo fixes, removing compiler warnings, etc.
+
+## Sign the Contributor License Agreement
+
+If you have not previously done so, please fill out and submit the
+[SpringSource CLA form][]. You'll receive a token when this process is complete.
+Keep track of this; you may be asked for it later!
+
+Note that emailing/postal mailing a signed copy is _not_ necessary. Submission
+of the web form is all that is required.
+
+Once you've completed the web form, simply add the following in a comment on
+your pull request:
+
+    I have signed and agree to the terms of the SpringSource Individual
+    Contributor License Agreement.
+
+You do not need to include your token/id. Please add the statement above to all
+future pull requests as well, simply so that the Spring Framework team knows
+immediately that this process is complete.
+
+
+## Create your branch from `3.2.x`
+
+If your pull request addresses a bug or improvement, please create your branch
+from Spring Framework's `3.2.x` branch. `master` is reserved for work on new features
+for the next major version of the framework. Rest assured that if your pull
+request is accepted and merged into `3.2.x`, these changes will also eventually
+be merged into `master`.
+
+
+## Use short branch names
+
+Branches used when submitting pull requests should preferably be named
+according to JIRA issues, e.g. 'SPR-1234'. Otherwise, use succinct, lower-case,
+dash (-) delimited names, such as 'fix-warnings', 'fix-typo', etc. In
+[fork-and-edit][] cases, the GitHub default 'patch-1' is fine as well. This is
+important, because branch names show up in the merge commits that result from
+accepting pull requests, and should be as expressive and concise as possible.
+
+
+## Mind the whitespace
+
+Please carefully follow the whitespace and formatting conventions already
+present in the framework.
+
+1. Tabs, not spaces
+1. Unix (LF), not DOS (CRLF) line endings
+1. Eliminate all trailing whitespace
+1. Wrap Javadoc at 90 characters
+1. Aim to wrap code at 90 characters, but favor readability over wrapping
+1. Preserve existing formatting; i.e. do not reformat code for its own sake
+1. Search the codebase using `git grep` and other tools to discover common
+   naming conventions, etc.
+1. Latin-1 (ISO-8859-1) encoding for Java sources; use `native2ascii` to convert
+   if necessary
+
+
+## Add Apache license header to all new classes
+
+```java
+/*

+ * distributed under the License is distributed on an "AS IS" BASIS,
+ * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.
+ * See the License for the specific language governing permissions and
+ * limitations under the License.
+ */
+
+package ...;
+```
+
+## Update Apache license header to modified files as necessary
+
+Always check the date range in the license header. For example, if you've
+modified a file in 2013 whose header still reads
+
+```java
+ * Copyright 2002-2011 the original author or authors.
+```
+
+then be sure to update it to 2013 appropriately
+
+```java
+ * Copyright 2002-2013 the original author or authors.
+```
+
+## Use @since tags for newly-added public API types and methods
+
+e.g.
+
+```java
+/**
+ * ...
+ *
+ * @author First Last
+ * @since 3.2
+ * @see ...
+ */
+```
+
+## Submit JUnit test cases for all behavior changes
+
+Search the codebase to find related unit tests and add additional @Test methods
+within. It is also acceptable to submit test cases on a per JIRA issue basis,
+e.g.
+
+```java
+package org.springframework.beans.factory.support;
+
+/**
+ * Unit tests for SPR-8954, in which a custom {@link InstantiationAwareBeanPostProcessor}
+ * forces the predicted type of a FactoryBean, effectively preventing retrieval of the
+ * bean from calls to #getBeansOfType(FactoryBean.class). The implementation of
+ * {@link AbstractBeanFactory#isFactoryBean(String, RootBeanDefinition)} now ensures
+ * that not only the predicted bean type is considered, but also the original bean
+ * definition's beanClass.
+ *
+ * @author Chris Beams
+ */
+public class Spr8954Tests {
+
+    @Test
+    public void cornerSpr8954() {
+        // ...
+    }
+}
+```
+
+
+## Squash commits
+
+Use `git rebase --interactive`, `git add --patch` and other tools to "squash"
+multiple commits into atomic changes. In addition to the man pages for git,
+there are many resources online to help you understand how these tools work.
+Here is one: https://book.git-scm.com/4_interactive_rebasing.html.
+
+
+## Use real name in git commits
+
+Please configure git to use your real first and last name for any commits you
+intend to submit as pull requests. For example, this is not acceptable:
+
+    Author: Nickname <user@mail.com>
+
+Rather, please include your first and last name, properly capitalized, as
+submitted against the SpringSource contributor license agreement:
+
+    Author: First Last <user@mail.com>
+
+This helps ensure traceability against the CLA, and also goes a long way to
+ensuring useful output from tools like `git shortlog` and others.
+
+You can configure this globally via the account admin area GitHub (useful for
+fork-and-edit cases); globally with
+
+    git config --global user.name "First Last"
+    git config --global user.email user@mail.com
+
+or locally for the spring-framework repository only by omitting the '--global'
+flag:
+
+    cd spring-framework
+    git config user.name "First Last"
+    git config user.email user@mail.com
+
+
+## Format commit messages
+
+Please read and follow the [commit guidelines section of Pro Git][].
+
+Most importantly, please format your commit messages in the following way
+(adapted from the commit template in the link above):
+
+    Short (50 chars or less) summary of changes
+
+    More detailed explanatory text, if necessary. Wrap it to about 72
+    characters or so. In some contexts, the first line is treated as the
+    subject of an email and the rest of the text as the body. The blank
+    line separating the summary from the body is critical (unless you omit
+    the body entirely); tools like rebase can get confused if you run the
+    two together.
+
+    Further paragraphs come after blank lines.
+
+     - Bullet points are okay, too
+
+     - Typically a hyphen or asterisk is used for the bullet, preceded by a
+       single space, with blank lines in between, but conventions vary here
+
+    Issue: SPR-1234, SPR-1235
+
+
+1. Use imperative statements in the subject line, e.g. "Fix broken Javadoc link"
+1. Begin the subject line sentence with a capitalized verb, e.g. "Add, Prune,
+   Fix, Introduce, Avoid, etc."
+1. Do not end the subject line with a period
+1. Keep the subject line to 50 characters or less if possible
+1. Wrap lines in the body at 72 characters or less
+1. Mention associated JIRA issue(s) at the end of the commit comment, prefixed
+   with "Issue: " as above
+1. In the body of the commit message, explain how things worked before this
+   commit, what has changed, and how things work now
+
+For examples of this style, issue a `git log --author=cbeams` in the
+spring-framework git repository. For convenience, here are several such commits:
+
+https://github.com/SpringSource/spring-framework/commit/08e2669b84ec0faa2f7904441fe39ac70b65b078
+https://github.com/SpringSource/spring-framework/commit/1d9d3e6ff79ce9f0eca03b02cd1df705925575da
+https://github.com/SpringSource/spring-framework/commit/8e0b1c3a5f957af3049cfa0438317177e16d6de6
+https://github.com/SpringSource/spring-framework/commit/b787a68f2050df179f7036b209aa741230a02477
+
+## Run all tests prior to submission
+
+See the [building from source][] section of the README for instructions. Make
+sure that all tests pass prior to submitting your pull request.
+
+
+## Submit your pull request
+
+Subject line:
+
+Follow the same conventions for pull request subject lines as mentioned above
+for commit message subject lines.
+
+In the body:
+
+1. Explain your use case. What led you to submit this change? Why were existing
+    mechanisms in the framework insufficient? Make a case that this is a
+    general-purpose problem and that yours is a general-purpose solution, etc.
+1. Add any additional information and ask questions; start a conversation, or
+    continue one from JIRA
+1. Mention the JIRA issue ID
+1. Also mention that you have submitted the CLA as described above
+
+Note that for pull requests containing a single commit, GitHub will default the
+subject line and body of the pull request to match the subject line and body of
+the commit message. This is fine, but please also include the items above in the
+body of the request.
+
+
+## Mention your pull request on the associated JIRA issue
+
+Add a comment to the associated JIRA issue(s) linking to your new pull request.
+
+
+## Expect discussion and rework
+
+The Spring team takes a very conservative approach to accepting contributions to
+the framework. This is to keep code quality and stability as high as possible,
+and to keep complexity at a minimum. Your changes, if accepted, may be heavily
+modified prior to merging. You will retain "Author:" attribution for your Git
+commits granted that the bulk of your changes remain intact. You may be asked to
+rework the submission for style (as explained above) and/or substance. Again, we
+strongly recommend discussing any serious submissions with the Spring Framework 
+team _prior_ to engaging in serious development work.
+
+Note that you can always force push (`git push -f`) reworked / rebased commits
+against the branch used to submit your pull request. i.e. you do not need to
+issue a new pull request when asked to make changes.

+		  GNU LESSER GENERAL PUBLIC LICENSE
+		       Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+		  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+  
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+			    NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.

+
+The file jdiff.html contains the reference page for JDiff.  The latest

+
+JDiff uses Xerces 1.4.2 from https://www.apache.org.
+
+JDiff also includes a script to use the classdoc application from
+http://classdoc.sourceforge.net or http://www.jensgulden.de, by Jens
+Gulden, (mail@jensgulden.de), to call a doclet such as jdiff on a .jar

+Arturo Fuente for his consistently fine cigars which helped inspire
+much of this work.

 ## Known issues
 
-1. MockServletContext and friends will fail to compile in spring-web. To fix this, uncheck the 'export' setting for all servlet-api and tomcat-servlet-api jars. The problem is that spring-web needs Servlet 2.5, but it's picking up Servlet 3.0 from projects that it depends on.
-2. spring-context will fail to build because there's a duplicate instance of GroovyMessenger in spring-context/src/test/java/org/springframework/scripting/groovy/Messenger.groovy. The solution to this is not known.  It's not a problem on Eclipse, because Eclipse doesn't automatically compile .groovy files like IDEA (apparently) does.

+See https://youtrack.jetbrains.com/issue/IDEA-64446 for details. In the meantime, the 'spring-aspects'

+2. While all JUnit tests pass from the command line with Gradle, many will fail when run from IDEA.
