Release version 3.2.4.RELEASE

Disable by default external entity resolution when using Spring OXM
with jaxb. This prevents a XML entity from being able to resolve a
local file on the host system.

See:
https://www.owasp.org/index.php/XML_External_Entity_(XXE)_Processing

Issue: SPR-10806
(cherry picked from commit 7576274)

+_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._
 
-First off, thank you for taking the time to contribute! :+1: :tada: 
+_Please refer back to this document as a checklist before issuing any pull
+request; this will save time for everyone!_

-### Code of Conduct
 
-This project is governed by the [Spring Code of Conduct](CODE_OF_CONDUCT.adoc).
-By participating you are expected to uphold this code.
-Please report unacceptable behavior to spring-code-of-conduct@pivotal.io.
+## Search JIRA first; create an issue if necessary
 
-### How to Contribute
+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.
 
-#### Discuss
+## Discuss non-trivial contribution ideas with committers
 
-If you have a question, check StackOverflow using
-[this list of tags](https://spring.io/questions), organized by Spring project.
-Find an existing discussion or start a new one if necessary.
+If you're considering anything more than correcting a typo or fixing a minor
+bug, please discuss it on the [spring-framework-contrib][] mailing list before
+submitting a pull request. We're happy to provide guidance, but please spend an
+hour or two researching the subject on your own including searching the mailing
+list for prior discussions.
 
-If you suspect an issue, perform a search in the
-[JIRA issue tracker](https://jira.spring.io/browse/SPR), using a few different keywords.
-When you find related issues and discussions, prior or current, it helps you to learn and
-it helps us to make a decision.
+## Sign the Contributor License Agreement
 
-#### Create a Ticket
+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!
 
-Reporting an issue or making a feature request is a great way to contribute. Your feedback
-and the conversations that result from it provide a continuous flow of ideas. 
+Note that emailing/postal mailing a signed copy is _not_ necessary. Submission
+of the web form is all that is required.
 
-Before you create a ticket, please take the time to [research first](#discuss).
+Once you've completed the web form, simply add the following in a comment on
+your pull request:
 
-If creating a ticket after a discussion on StackOverflow, please provide a self-sufficient description in the ticket, independent of the details on StackOverview. We understand this is extra work but the issue tracker is an important place of record for design discussions and decisions that can often be referenced long after the fix version, for example to revisit decisions, to understand the origin of a feature, and so on.
+    I have signed and agree to the terms of the SpringSource Individual
+    Contributor License Agreement.
 
-When ready create a ticket in the [JIRA issue tracker](https://jira.spring.io/browse/SPR).
+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.
 
-#### Ticket Lifecycle
 
-When an issue is first created, it may not be assigned and will not have a fix version.
-Within a day or two, the issue is assigned to a specific committer and the target
-version is set to "Waiting for Triage". The committer will then review the issue, ask for
-further information if needed, and based on the findings, the issue is either assigned a fix
-version or rejected.
+## Create your branch from `3.2.x`
 
-When a fix is ready, the issue is marked "Resolved" and may still be re-opened. Once a fix
-is released, the issue is permanently "Closed". If necessary, you will need to create a new,
-related ticket with a fresh description.
+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`.
 
-#### Submit a Pull Request
 
-You can contribute a source code change by submitting a pull request.
+## Use short branch names
 
-1. If you have not previously done so, please sign the
-[Contributor License Agreement](https://cla.pivotal.io/sign/spring). You will also be reminded
-automatically when you submit a pull request.
+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.
 
-1. For all but the most trivial of contributions, please [create a ticket](#create-a-ticket).
-The purpose of the ticket is to understand and discuss the underlying issue or feature.
-We use the JIRA issue tracker as the preferred place of record for conversations and
-conclusions. In that sense discussions directly under a PR are more implementation detail
-oriented and transient in nature.
 
-1. Always check out the `master` branch and submit pull requests against it
-(for target version see [settings.gradle](settings.gradle)).
-Backports to prior versions will be considered on a case-by-case basis and reflected as
-the fix version in the issue tracker.
+## Mind the whitespace
 
-1. Use short branch names, preferably based on the JIRA issue (e.g. `SPR-1234`), or
-otherwise using succinct, lower-case, dash (-) delimited names, such as `fix-warnings'.
+Please carefully follow the whitespace and formatting conventions already
+present in the framework.
 
-1. Choose the granularity of your commits consciously and squash commits that represent
-multiple edits or corrections of the same logical change. See
-[Rewriting History section of Pro Git](https://git-scm.com/book/en/Git-Tools-Rewriting-History)
-for an overview of streamlining commit history.
+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
 
-1. Format commit messages using 55 characters for the subject line, 72 lines for the
-description, followed by related issues, e.g. `Issues: SPR-1234, SPR-1235`.
-See the
-[Commit Guidelines section of Pro Git](https://git-scm.com/book/en/Distributed-Git-Contributing-to-a-Project#Commit-Guidelines)
-for best practices around commit messages and use `git log` to see some examples.
 
-1. List the JIRA issue number in the PR description.
+## Add Apache license header to all new classes
 
-If accepted, your contribution may be heavily modified as needed prior to merging.
-You will likely retain author attribution for your Git commits granted that the bulk of
-your changes remain intact. You may also be asked to rework the submission.

-See the [Build from Source](https://github.com/spring-projects/spring-framework/wiki/Build-from-Source)
-wiki page for instructions on how to check out, build, and import the Spring Framework

+```
 
-The wiki pages
-[Code Style](https://github.com/spring-projects/spring-framework/wiki/Code-Style) and

-defines the source file coding standards we use along with some IDEA editor settings we customize.
+then be sure to update it to 2013 appropriately
 
-### Reference Docs
+```java
+ * Copyright 2002-2013 the original author or authors.
+```
 
-The reference documentation is in the [src/docs/asciidoc](src/docs/asciidoc) directory and, in
-[Asciidoctor](https://asciidoctor.org/) format. For trivial changes, you may be able to browse,
-edit source files, and submit directly from Github.
+## Use @since tags for newly-added public API types and methods
 
-When making changes locally, use `./gradlew asciidoctor` and then browse the result under
-`build/asciidoc/html5/index.html`.
+e.g.
 
-Asciidoctor also supports live editing. For more details read
-[Editing AsciiDoc with Live Preview](https://asciidoctor.org/docs/editing-asciidoc-with-live-preview/).
-Note that if you choose the
-[System Monitor](https://asciidoctor.org/docs/editing-asciidoc-with-live-preview/#using-a-system-monitor)
-option, you can find a Guardfile under `src/docs/asciidoc`.
+```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: http://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.

-# <img src="src/docs/asciidoc/images/spring-framework.png" width="80" height="80"> Spring Framework
+## Spring Framework
+The Spring Framework provides a comprehensive programming and configuration
+model for modern Java-based enterprise applications - on any kind of deployment
+platform. A key element of Spring is infrastructural support at the application
+level: Spring focuses on the "plumbing" of enterprise applications so that teams
+can focus on application-level business logic, without unnecessary ties to
+specific deployment environments.
 
-This is the home of the Spring Framework, the foundation for all
-[Spring projects](https://spring.io/projects). Together the Spring Framework and the family of Spring projects make up what we call "Spring". 
+The framework also serves as the foundation for [Spring Integration][], [Spring
+Batch][] and the rest of the Spring [family of projects][]. Browse the
+repositories under the [SpringSource organization][] on GitHub for a full list.
 
-Spring provides everything you need beyond the Java language to create enterprise
-applications in a wide range of scenarios and architectures. Please read the
-[Overview](https://docs.spring.io/spring/docs/current/spring-framework-reference/overview.html#spring-introduction)
-section in the reference for a more complete introduction.
+[.NET][] and [Python][] variants are available as well.
 
-## Code of Conduct
-
-This project is governed by the [Spring Code of Conduct](CODE_OF_CONDUCT.adoc).
-By participating you are expected to uphold this code.
-Please report unacceptable behavior to spring-code-of-conduct@pivotal.io.
-
-## Access to Binaries
-
-For access to artifacts or a distribution zip, see the
-[Spring Framework Artifacts](https://github.com/spring-projects/spring-framework/wiki/Spring-Framework-Artifacts)
-wiki page.
+## Downloading artifacts
+See [downloading Spring artifacts][] for Maven repository information. Unable to
+use Maven or other transitive dependency management tools? See [building a
+distribution with dependencies][].
 
 ## Documentation
+See the current [Javadoc][] and [reference docs][].
 
-The Spring Frameworks maintains reference documentation
-([published](https://docs.spring.io/spring-framework/docs/current/spring-framework-reference/) and
-[source](src/docs/asciidoc)),
-Github [wiki pages](https://github.com/spring-projects/spring-framework/wiki), and an
-[API reference](https://docs.spring.io/spring-framework/docs/current/javadoc-api/).
-There are also [guides and tutorials](https://spring.io/guides) across Spring projects.
+## Getting support
+Check out the [Spring forums][] and the [spring][spring tag] and
+[spring-mvc][spring-mvc tag] tags on [Stack Overflow][]. [Commercial support][]
+is available too.
 
-## Build from Source
+## Issue Tracking
+Report issues via the [Spring Framework JIRA]. Understand our issue management
+process by reading about [the lifecycle of an issue][]. Think you've found a
+bug? Please consider submitting a reproduction project via the
+[spring-framework-issues][] GitHub repository. The [readme][] there provides
+simple step-by-step instructions.
 
-See the [Build from Source](https://github.com/spring-projects/spring-framework/wiki/Build-from-Source)
-wiki page and also [CONTRIBUTING.md](CONTRIBUTING.md).
+## Building from source
+The Spring Framework uses a [Gradle][]-based build system. In the instructions
+below, [`./gradlew`][] is invoked from the root of the source tree and serves as
+a cross-platform, self-contained bootstrap mechanism for the build. The only
+prerequisites are [Git][] and JDK 1.7+.

+The following has been tested against Intellij IDEA 12.0
 
 ## Steps
 
 _Within your locally cloned spring-framework working directory:_
 
-1. Precompile `spring-oxm` with `./gradlew :spring-oxm:compileTestJava`
-2. Import into IntelliJ (File -> New -> Project from Existing Sources -> Navigate to directory -> Select build.gradle)
-3. When prompted exclude the `spring-aspects` module (or after the import via File-> Project Structure -> Modules)
-4. Code away
+1. Generate IDEA metadata with `./gradlew :spring-oxm:compileTestJava cleanIdea idea`
+2. Import into IDEA as usual
+3. Set the Project JDK as appropriate
+4. Add git support
+5. Code away
 
 ## Known issues
 
-1. `spring-core` and `spring-oxm` should be pre-compiled due to repackaged dependencies.
-See `*RepackJar` tasks in the build and https://youtrack.jetbrains.com/issue/IDEA-160605).
-2. `spring-aspects` does not compile due to references to aspect types unknown to
-IntelliJ IDEA. See https://youtrack.jetbrains.com/issue/IDEA-64446 for details. In the meantime, the
-'spring-aspects' can be excluded from the project to avoid compilation errors.
-3. While JUnit tests pass from the command line with Gradle, some may fail when run from
-IntelliJ IDEA. Resolving this is a work in progress. If attempting to run all JUnit tests from within
-IntelliJ IDEA, you will likely need to set the following VM options to avoid out of memory errors:
+1. `spring-aspects` does not compile out of the box due to references to aspect types unknown to IDEA.

     -XX:MaxPermSize=2048m -Xmx2048m -XX:MaxHeapSize=2048m
-4. If you invoke "Rebuild Project" in the IDE, you'll have to generate some test
-resources of the `spring-oxm` module again (`./gradlew :spring-oxm:compileTestJava`)
