Closes gh-31952
This change moves container element properties from ParameterErrors

Prior to this commit, the `HandlerMappingIntrospector` would comparea
request with a cached request by using `String#matches` on their String
URI. This could lead to `PatternSyntaxException` exceptions at runtime
if the request URI contained pattern characters.
This commit fixes this typo to use `String#equals` instead.

This commit adds a functional style registration of an application
listener for a particular event. Rather than introducing another method
at the ConfigurableApplicationContext interface level, this commit
provides a factory method in GenericApplicationListener.
Closes gh-21411
Prior to this commit, the `DefaultScheduledTaskObservationConvention`
would fail as it tried to add a `KeyValue` to the observation context
that is `null`. This is rejected by the observation registry and should
be prevented. This happened when registered scheduled methods were
lambdas or part of anonymous classes. Those types do not have a
canonical name and return `null` as a value there.
This commit ensures that for these cases, the default convetion uses a
`"ANONYMOUS"` value as the `"code.namespace"` keyvalue.

After the updates to MethodValidationAdapter in commit d7ce13 related

This commit restores support for Kotlin extensions in
web handlers, and adds support for invoking reflectively
suspending extension functions, as well as the other
features supported as of Spring Framework 6.1 like
value classes and default value for parameters.
Closes gh-31876
The goal for #31530 was to support bean validation on Set and other
method parameters that are containers of value(s) for which there is
a registered Jakarta Validation ValueExtractor.
Unfortunately, bean validation does not expose the unwrapped value
for a Path.Node, which we need for a method parameter in order to
create a BindingResult for the specific bean within the container,
and the leafBean that we tried to use is really the node at the
very bottom of the property path (i.e. not what we need).
This change removes the use of beanLeaf, restores the logic as it
was before, adds support for arrays, and a new test class for
scenarios with cascaded violations.
See gh-31746
Prior to this commit, the `WebHttpHandlerBuilder` would only configure
a custom observation convention if there is a single convention in the
application context. It would other wise use the default.
This commit aligns with the previous Spring Boot behavior where multiple
conventions setups are rejected as invalid with
`NoUniqueBeanDefinitionException`.
Fixes gh-31864
This commit refines InvocableHandlerMethod (both Servlet and
Reactive variants) in order to support annotated property

of throwing a NullPointerException.
Closes gh-31856
DataBinder should skip any jakarta.validation.Validator yielding
to method validation when that is expected. This change improves
the check to skip by unwrapping the validator from in a
SmartValidator before checking if it is for bean validation.
Closes gh-31711
Method validation needs to be used for a container such as a List or
Map, but until now we were only checking for a List container.
Moreover, in gh-31530 we improved method validation to also cover
any Collection.
This change aligns with HandlerMethod check for when method validation
applies with the underlying ability of method validation.
This commit improves JettyWebSocketHandlerAdapter::copyByteBuffer so
that it allocates a buffer large enough for the remaining bytes
contained in the source, instead of allocating one with the capacity of
the source.
Closes gh-31857
This commit updates the JSON writers to use a deterministic order for
arrays. Previously, the order could change with the same content,
breaking caching.
Closes gh-31852
This commit ensures that the capacity of the remainder buffer after a
split operation is set directly on the field. Calling capacity(int)
caused a new buffer to be allocated.
Closes gh-31848
This commit builds on top of changes made in gh-29775 and gh-31737.
Before this change, we would allocate several byte arrays even in cases
of known request size. This could decrease performance when getting the
cached content as it requires merging several arrays and data is not
colocated in memory.
This change ensures that we create a `FastByteArrayOutputStream`
instance with the known request size so that the first allocated segment
can contain the entire content.
If the request size is not know, we will default back on the default
allocation size for the `FastByteArrayOutputStream`.
Closes gh-31834

This commits allows ValueCodeGenerator$Delegate implementations to be
loaded from `META-INF/spring/aot.factories` and considered for code
generation of bean definition property values. This default behavior
in DefaultBeanRegistrationCodeFragments can be customized as usual.
Closes gh-31427
This commit introduces ValueCodeGenerator and its Delegate interface
as a way to generate the code for a particular value. Implementations
in spring-core provides support for common value types such a String,
primitives, Collections, etc.
Additional implementations are provided for code generation of bean
definition property values.
Closes gh-28999
Prior to this commit, the AnnotationsScanner used in the
MergedAnnotations infrastructure found duplicate annotations on methods
within multi-level interface hierarchies.
This commit addresses this issue by scanning methods at a given level
in the interface hierarchy using ReflectionUtils#getDeclaredMethods
instead of Class#getMethods, since the latter includes public methods
declared in super-interfaces which will anyway be scanned when
processing super-interfaces recursively.
Closes gh-31803
This commit matches the behavior of the core container when it
invokes a custom init or destroy method. If the custom method is an
interface implementation, the core container attempts to invoke the
method that's defined on the interface. This commit makes sure to also
register a hint for the interface method.
Closes gh-31819
Prior to this commit, the WebClient observations would have a specific
lifecycle where the observation context is build with a
`ClientRequest.Builder` as tracing needs to add an outgoing request
header before the request is made immutable.
With this setup, the metrics observation handler processes the start
event by increasing the "http.client.requests.active" counter and
collecting tags at this point. Because then the immutable request is not
yet fully built or set on the context, the keyvalues collected by the
observation convention at that point can be incomplete.
This commit ensures that a request is always made available in the
context, even if it is updated right after the observation start. The
only difference between the two should be additional tracing headers and
a request attribute holding the current observation context.
Closes gh-31702
This commit documents the fact that any (Unchecked)IOExceptions or
HttpMessageNotReadableExceptions thrown from the error handler will be
wrapped in a RestClientException.
Closes gh-31783
Prior to this commit, the `ConcurrentReferenceHashMap#restructure`
operation would null out the entire references array before starting the
restructuring operation (in case resizing is not necessary).
This could cause at runtime race conditions where a lookup operation
would return null, when the value is actually cached but not accesible
during the restructuring phase.
This commit ensures that, when resizing is not required, a new reference
list is built (purged of null entries) and then assigned to the
reference array. This way, concurrent reads will not return null for
existing entries and there are less chances of re-calculating cache
entries during the restructuring phase.
Closes gh-31008
Required by Spring Security to complete work on
https://github.com/spring-projects/spring-security/issues/14128
The setCache and resetCache methods used from createCacheFilter are now
public. Generally they don't need to be used outside of the Filter if
only making checks against the current request. Spring Security, however,

Commit 33454a4007 introduced a regression in Comparators.nullsLow() and

Introduce ShardingKeyDataSourceAdapter to get shard connections.
This commit introduces a DataSource proxy, that changes the behavior of the getConnection method to use the `createConnectionBuilder()` api to acquire direct shard connections. The shard connection is acquired by specifying a `ShardingKey` that is correspondent to the wanted shard.
While it is not easily possible to create a ConcurrentTaskScheduler
with no scheduled executor, DefaultManagedTaskScheduler has a default
constructor that does that as the JNDI lookup happens in the regular
afterPropertiesSet callback. If such an instance is created manually,
it can throw an unhelpful NullPointerException if one attempts to
schedule a task.
This commit updates ConcurrentTaskScheduler to flag that the scheduled
executor could be `null` and check if that's the case before using it.
This now throws a dedicated exception that should hopefully provide
better context for those upgrading.

In gh-30549 we applied changes to the `DefaultPersistenceUnitManager` to
use the `ValidationMode.CALLBACK` to better detect invalid validation
setup and enforce bootstrap failures in those cases.
Unfortunately, doing so disables the detection of validation annotation
on entities during the schema creation phase. This is a known Hibernate
issue. This commit reverts this change until HHH-12287 is fixed.

Work performed in conjunction with gh-30941 resulted in a regression.
Specifically, prior to Spring Framework 6.1 a locally declared
@ComponentScan annotation took precedence over @ComponentScan
meta-annotations, which allowed "local" configuration to override

This commit modifies the @ComponentScan search algorithm so that
locally declared @ComponentScan annotations are once again favored
over @ComponentScan meta-annotations (and, indirectly, composed
annotations).

This commit introduces a toString() overload in
FastByteArrayOutputStream that accepts a Charset in order to mirror the
method that was introduced in ByteArrayOutputStream in JDK 10,

This commit also updates getContentAsString() in
ContentCachingRequestWrapper to use this new toString(Charset) method.
Closes gh-31737
This commit ensures that the RestClient uses the
IntrospectingClientHttpResponse to verify whether the response has a
body, and return null if it does not.
See gh-12671
Closes gh-31719
The getContentAsString method was originally added in d9b8826 to avoid
the extra copying inherent to calling ByteArrayOutputStream.toByteArray;
however, in f83c609 the class was updated to instead use
FastByteArrayOutputStream, and in the process the extra copy was brought
back when getContentAsString was changed to call toByteArray.
Switch to calling toByteArrayUnsafe, a method provided by
FastByteArrayOutputStream, which avoids the extra copy; since we
immediately pass the byte array to the String constructor, and it isn't
accessed anywhere else, the usage is safe.

This commit allows to define a bean order programmatically

See gh-30849
Prior to this commit, regressions were introduced with gh-31417:
1. the observation keyvalues would be inconsistent with the HTTP response
2. the observation scope would not cover all controller handlers, causing
traceIds to be missing
The first issue is caused by the fact that in case of error signals, the
observation was stopped before the response was fully committed, which
means further processing could happen and update the response status.
This commit delays the stop event until the response is committed in
case of errors.
The second problem is caused by the change from a `contextWrite`
operator to using the `tap` operator with a `SignalListener`. The
observation was started in the `doOnSubscription` callback, which is too
late in some cases. If the WebFlux controller handler is synchronous
non-blocking, the execution of the handler is performed before the
subscription happens. This means that for those handlers, the
observation was not started, even if the current observation was
present in the reactor context. This commit changes the
`doOnSubscription` to `doFirst` to ensure that the observation is
started at the right time.

This changes ensures RequestMappingInfo uses PathPatternParser by default
as all AbstractHandlerMapping implementations do as of 6.0.
RequestMappingInfo instances are typically created internally and aligned with
the RequestMappingHandlerMapping in terms of path mapping options.
If a RequestMappingInfo is registered programmatically, the caller needs to also
ensure they are aligned. However, if the two should be aligned by default.

Prior to this commit, the TestContextManager logged an exception from a
TestExecutionListener at WARN level except in prepareTestInstance()

This commit makes sure to initialize any HandlerMapping defined in the
context when searching for resource handlers. Previously, the detection
algorithm was looking up for `SimpleUrlHandlerMapping` while the
declared target type in WebMvcConfigurationSupport is HandlerMapping.
If the application uses lazy initialization, the lookup algorithm would
not force that bean to be initialized.
Closes gh-25488
Prior to this commit, any time an aborted/skipped exception was thrown
by a TestExecutionListener, the TestContextManager unconditionally
logged the exception at WARN level -- or ERROR level for
prepareTestInstance() callbacks.
Regarding the latter, an aborted/skipped exception is certainly not an
ERROR, and in general the associated log output is very verbose
(including a stack trace) and not something the user should be warned
about it.
To improve the user experience, this commit revises TestContextManager
so that it logs such exceptions at INFO level.
Specifically, the following types of exceptions are considered
aborted/skipped exceptions.
- JUnit Jupiter: org.opentest4j.TestAbortedException
- JUnit 4 org.junit.AssumptionViolatedException
- TestNG: org.testng.SkipException

The documentation currently states that Inversion of Control (IoC) and
Dependency Injection (DI) are the same thing. Although the two terms

fundamental concepts of software frameworks.

Prior to this commit, `ExchangeFilterFunction` could only get the
current observation from the reactor context. This is particularly

behavior with other instrumentations.

Prior to this commit, the Jackson 2.x encoders, in case of encoding a
stream of data, would first release the `ByteArrayBuilder` and then the
`JsonGenerator`. This order is inconsistent with the single value
variant (see `o.s.h.codec.json.AbstractJackson2Encoder#encodeValue`) and
invalid since the `JsonGenerator` uses internally the
`ByteArrayBuilder`.
In case of a CSV Encoder, the codec can buffer data to write the column
names of the CSV file. Writing an empty Flux with this Encoder would not
fail but still log a NullPointerException ignored by the reactive
pipeline.
This commit fixes the order and avoid such issues at runtime.

Prior to this commit, the getResource() methods in PathResourceResolver

intended.
This commit modifies the getResource() methods in PathResourceResolver
implementations so that the log messages include the output of the
toString() implementations of the underlying resources instead of their
getURL() implementations, which may throw an exception.
Furthermore, logging the toString() output of resources aligns with the
existing output for "allowed locations" in the same log message.
Note that the toString() implementations could potentially also throw
exceptions, but that is considered less likely.

Commit d3fba6d49b introduced built-in pattern matching support for
method names in ControlFlowPointcut; however, it was still cumbersome
to extend ControlFlowPointcut with support for regular expressions
instead of simple pattern matching.
To address that, this commit introduces a variant of isMatch() that
accepts the pattern index instead of the pre-resolved method name
pattern. The default implementation retrieves the method name pattern
from the methodNamePatterns field and delegates to isMatch(String, String).
Subclasses can override the new isMatch(String, int) method to support
regular expressions, as can be seen in the example
RegExControlFlowPointcut class in ControlFlowPointcutTests.
See gh-31435
This commit fixes code generation when an indexed constructor argument
value is null as the method is overloaded and need the value to be
cast to `Object`.
Closes gh-31508
Prior to this commit, ControlFlowPointcut supported a single method
name which was matched exactly. Although it was possible to extend
ControlFlowPointcut to add support for pattern matching, it was a bit
cumbersome.
To address that, this commit introduces built-in pattern matching
support for method names in ControlFlowPointcut, analogous to the
pattern matching support in NameMatchMethodPointcut.
Specifically, a user can provide one or more method name patterns, and
the patterns will be matched against candidate method names using OR
semantics.
By default, the matching algorithm delegates to
PatternMatchUtils.simpleMatch(), but this can be overridden in
subclasses by overriding the new protected isMatch() method.
Closes gh-31435
Previously, ConstructorResolver would reject any candidate if the
parameter is `null`. The reason for that is that null does not carry
any type and the matching algorithm would systematically fail for that
argument.
This commit adds an extra check, and several tests, to validate that
a null value is taken into account.
Closes gh-31495
Prior to this commit, @SpringJUnitConfig and @SpringJUnitWebConfig
did not declare `loader` attributes that alias @ContextConfiguration's
`loader` attribute. Consequently, it was not possible to configure a

introduces them to support custom ContextLoader configuration directly
via the @SpringJUnitConfig and @SpringJUnitWebConfig annotations.

Prior to this commit, the `ConcurrentReferenceHashMap#Segment` would
recalculate its element count during the restructure phase by
subtracting the number of polled elements from the queue to the current
count.
Later, the newly restructured `references` array would only contain
references that 1) are not in the set of elements to purge and
2) that hold a non-null value.
The issues with this approach are multiple. The newly calculated count
is only an estimate, as some situations can make it invalid, even
temporarily.
* since we initially collected all elements to be purged from the queue,
the GC might have collected new values. This means that we might
filter out more references that we initially intended to
* because the restructure operation re-creates new references for all
elements in the original array, we might later get references from the
queue that are not in the array anymore. This could lead to
"duplicate" removals for the same value
Because several methods in the Segment class have special no-op behavior
when `count == 0`, an invalid count can lead to keys appearing missing
when they are actually still present. In some scenarios, this can
decrease the performance of the cache since values need to be
recalculated.
This commit fixes this inconsistency count issue by first using an
estimate in order to decide whether the array needs a resize and then by
counting the actual numbers of elements inserted in the restructured
array as the new count.

This commit applies @DisabledInAotMode to test classes in the
spring-test module that will never be able to be processed for AOT
optimizations.
Test classes that fail for reasons that can potentially be addressed in
a future version of the framework have not been annotated with
@DisabledInAotMode.
See gh-29122
Although it should not happen in theory, sometimes a test class is
discovered more than once via the TestClassScanner in our integration
tests. When it does happen in our tests, the two Class objects have the
same fully-qualified class name but represent different classes which
leads to failures due to incorrect associations between test class
names and their MergedContextConfiguration.
To address this, this commit modifies TestContextAotGenerator so that
it skips duplicate test class names.
This commit adds Coroutines support for `@Cacheable`.
It also refines SimpleKeyGenerator to ignore Continuation

Since the Spring WebFlux HTTP server instrumentation has been moved from
the `WebFilter` to the `HttpWebHandlerAdapter`, we need to apply similar
changes there.
See gh-31417
Prior to this commit, HTTP server observations for Spring WebFlux could
be recorded twice for a single request in some cases. The "COMPLETE" and
"CANCEL" signals would race in the reactive pipeline and would trigger
both the `doOnComplete()` and ` `doOnCancel()` operators, each calling
`observation.stop()` on the current observation.
This would in fact publish two different observations for the same
request.
This commit ensures that the instrumentation uses the `Mono#tap`
operator to guard against this case and only call `Observation#stop`
once for each request.
Fixes gh-31417
This commit adds support for TypeStringValue when generating AOT code.
If the value does not specify an explicit type, it's specified as is.
Otherwise, the TypeStringValue instance is restored via the appropriate

Closes gh-29074
Prior to this commit, a cancelled exchange would always result in an
`"status":"UNKNOWN"` KeyValue. This only applied to reactive variants,
as cancelled exchanges are not currently detected for Servlet
implementations.
In some cases, exchanges can be cancelled by clients before they are
completed, but the response was actually received by the client. The
response status information has been set by the application and the
response has been committed. For those cases, we shouldn't assume an
"UNKNOWN" value.
This commit assumes that committed responses have a response status set
by the application and that the observations should reflect that. From
now on, we only assume an "UNKNOWN" status if the response has not been
commited.

Due to the changes in gh-31341, if the repeat count in a SpEL
expression (using the repeat operator '*') is negative, we throw a
SpelEvaluationException with the MAX_REPEATED_TEXT_SIZE_EXCEEDED
message which is incorrect and misleading.
Prior to gh-31341, a negative repeat count resulted in an
IllegalArgumentException being thrown by String#repeat(), which was
acceptable in terms of diagnostics, but that did not make it
immediately clear to the user what the underlying cause was.
In light of the above, this commit improves diagnostics for a negative
repeated text count in SpEL expressions by throwing a
SpelEvaluationException with a new NEGATIVE_REPEATED_TEXT_COUNT error
message.
Closes gh-31342
If the resulting size of repeated text in a SpEL expression (using the
repeat operator '*') would exceed MAX_REPEATED_TEXT_SIZE, we currently
throw a SpelEvaluationException with the
MAX_REPEATED_TEXT_SIZE_EXCEEDED message.
However, if the calculation of the repeated text size results in
integer overflow, our max size check fails to detect that, and
String#repeat(int) throws a preemptive OutOfMemoryError from which the
application immediately recovers.
To improve diagnostics for users, this commit ensures that we
consistently throw a SpelEvaluationException with the
MAX_REPEATED_TEXT_SIZE_EXCEEDED message when integer overflow occurs.
Closes gh-31341
Prior to this commit the Spring Expression Language (SpEL) was able to
properly parse an expression that uses the safe navigation operator
(?.) with a method that has a `void` return type (for example,
"myObject?.doSomething()"); however, SpEL was not able to evaluate or
compile such expressions.
This commit addresses the evaluation issue by selectively not boxing
the exit type descriptor (for inclusion in the generated bytecode) when
the method's return type is `void`.
This commit addresses the compilation issue by pushing a null object
reference onto the stack in the generated byte code when the method's
return type is `void`.

Prior to this commit, if a Spring Expression Language (SpEL) expression
contained property, field, or method references using the null-safe

representation of 'myProperty.myMethod()'.

Since the rewrite of ConcurrentLruCache in Spring Framework 6.0, an

Previously, MessagingMessageListenerAdapter or any adapter relying on
the default MessagingMessageConverter would log an incoming message
with a toString of the Message that does not provide any extra

when necessary.
This commit implements a toString method that uses the raw JMS message
if the payload is not available. If it is, the payload is used instead.

Given a @Configuration class named org.example.AppConfig which
contains @Bean methods, in Spring Framework 5.3.x and previous
versions, the following classes were created when generating the CGLIB
proxy.
org.example.AppConfig$$EnhancerBySpringCGLIB$$fd7e9baa
org.example.AppConfig$$FastClassBySpringCGLIB$$3fec86e
org.example.AppConfig$$EnhancerBySpringCGLIB$$fd7e9baa$$FastClassBySpringCGLIB$$82534900
Those class names indicate that 1 class was generated for the proxy for
the @Configuration class itself and that 2 additional FastClass
classes were generated to support proxying of @Bean methods in
superclasses.
However, since Spring Framework 6.0, the following classes are created
when generating the CGLIB proxy.
org.example.AppConfig$$SpringCGLIB$$0
org.example.AppConfig$$SpringCGLIB$$1
org.example.AppConfig$$SpringCGLIB$$2
The above class names make it appear that 3 proxy classes are generated
for each @Configuration class, which is misleading.
To address that and to align more closely with how such generated
classes were named in previous versions of the framework, this commit
modifies SpringNamingPolicy so that generated class names once again
include "FastClass" when the generated class is for a CGLIB FastClass
as opposed to the actual proxy for the @Configuration class.
Consequently, with this commit the following classes are created when
generating the CGLIB proxy.
org.example.AppConfig$$SpringCGLIB$$0
org.example.AppConfig$$SpringCGLIB$$FastClass$$0
org.example.AppConfig$$SpringCGLIB$$FastClass$$1

The introduction of AdvisedSupport.AdvisorKeyEntry in Spring Framework
6.0.10 resulted in a regression regarding caching of CGLIB generated
proxy classes. Specifically, equality checks for the proxy class cache
became based partially on identity rather than equivalence. For
example, if an ApplicationContext was configured to create a
class-based @Transactional proxy, a second attempt to create the
ApplicationContext resulted in a duplicate proxy class for the same
@Transactional component.
On the JVM this went unnoticed; however, when running Spring
integration tests within a native image, if a test made use of
@DirtiesContext, a second attempt to create the test
ApplicationContext resulted in an exception stating, "CGLIB runtime
enhancement not supported on native image." This is because Test AOT
processing only refreshes a test ApplicationContext once, and the
duplicate CGLIB proxy classes are only requested in subsequent
refreshes of the same ApplicationContext which means that duplicate
proxy classes are not tracked during AOT processing and consequently
not included in a native image.
This commit addresses this regression as follows.
- AdvisedSupport.AdvisorKeyEntry is now based on the toString()
representations of the ClassFilter and MethodMatcher in the
corresponding Pointcut instead of the filter's and matcher's
identities.
- Due to the above changes to AdvisorKeyEntry, ClassFilter and
MethodMatcher implementations are now required to implement equals(),
hashCode(), AND toString().
- Consequently, the following now include proper equals(), hashCode(),
and toString() implementations.
- CacheOperationSourcePointcut
- TransactionAttributeSourcePointcut
- PerTargetInstantiationModelPointcut

Prior to this commit, `ClassUtils#forName` would always attempt to
resolve the given class name as a nested type. For example, searching
for `org.example.Spring` would try to resolve:
* `org.example.Spring`
* if not available, try `org.example$Spring` as well
Java classes usually start with uppercase letters, so this additional
lookup can be costly and not very useful.
This commit only attempts nested class lookups when the previous segment
starts with an uppercase. So `org.example.Spring.Issue` will look for
`org.example.Spring$Issue`, but `org.example.Spring` will not.

Prior to this commit, the `RuntimeHintsPredicates` would assume that
registering introspection or invocation hints for "all declared methods"
on a type would also include "all public methods". This is not true, as

the latter can return inherited methods, but not the former.
Same reasoning applies to fields.

{spring-framework-api}/aot/hint/annotation/RegisterReflectionForBinding.html[`@RegisterReflectionForBinding`] is a specialization of `@Reflective` that registers the need for serializing arbitrary types.
A typical use case is the use of DTOs that the container cannot infer, such as using a web client within a method body.
`@RegisterReflectionForBinding` can be applied to any Spring bean at the class level, but it can also be applied directly to a method, field, or constructor to better indicate where the hints are actually required.
With `RuntimeHintsPredicates`, we can check for reflection, resource, serialization, or proxy generation hints.
This approach works well for unit tests but implies that the runtime behavior of a component is well known.

The Spring Framework integrates with checkpoint/restore as implemented by https://github.com/CRaC/docs[Project CRaC] in order to allow implementing systems capable of reducing the startup and warmup times of Spring-based Java applications with the JVM.
Using this feature requires:
* A checkpoint/restore enabled JVM (Linux only for now).
* The presence in the classpath of the https://github.com/CRaC/org.crac[`org.crac:crac`] library.
* Specifying the required `java` commandline parameters like `-XX:CRaCCheckpointTo=PATH` or `-XX:CRaCRestoreFrom=PATH`.
* The presence of the https://github.com/CRaC/org.crac[`org.crac:crac`] library (version `1.4.0` and above are supported) in the classpath.
* Specifying the required `java` command-line parameters like `-XX:CRaCCheckpointTo=PATH` or `-XX:CRaCRestoreFrom=PATH`.
WARNING: The files generated in the path specified by `-XX:CRaCCheckpointTo=PATH` when a checkpoint is requested contain a representation of the memory of the running JVM, which may contain secrets and other sensitive data. Using this feature should be done with the assumption that any value "seen" by the JVM, such as configuration properties coming from the environment, will be stored in those CRaC files. As a consequence, the security implications of where and how those files are generated, stored and accessed should be carefully assessed.

When the `-Dspring.context.checkpoint=onRefresh` JVM system property is set, a checkpoint is created automatically at

`InitializingBean#afterPropertiesSet` callbacks have been invoked; but the lifecycle has not started, and the
`ContextRefreshedEvent` has not yet been published.
For testing purposes, it is also possible to leverage the `-Dspring.context.exit=onRefresh` JVM system property which
triggers similar behavior, but instead of creating a checkpoint, it exits your Spring application at the same lifecycle
phase without requiring the Project CraC dependency/JVM or Linux. This can be useful to check if connections to remote
services are required when the beans are not started, and potentially refine the configuration to avoid that.
WARNING: As mentioned above, and especially in use cases where the CRaC files are shipped as part of a deployable artifact (a container image for example), operate with the assumption that any sensitive data "seen" by the JVM ends up in the CRaC files, and assess carefully the related security implications.
NOTE: Here checkpoint/restore is a way to "fast-forward" the startup of the application to a phase where the application context is about to start, but does not allow to have a fully warmed-up JVM.
