SingletonSupplier<T> supplier-based static methods nullability should
be refined to accept in a flexible way nullable or non-nullable T.

This commit reinstantiates checks for kotlin-reflect (via static final
fields for faster Java code paths and better native code removal) which
were removed as part of gh-34275, which did not consider the
increasingly popular use cases where kotlin-stdlib is present in the
classpath as a transitive dependency in Java applications.
Closes gh-35511
This commit apply several refinements to PropagationContextElement:
- Capture the ThreadLocal when instantiating the
PropagationContextElement in order to support dispatchers switching
threads
- Remove the constructor parameter which is not idiomatic and breaks
the support when switching threads, and use instead the
updateThreadContext(context: CoroutineContext) parameter
- Make the kotlinx-coroutines-reactor dependency optional
- Make the properties private
The Javadoc and tests are also updated to use the
`Dispatchers.IO + PropagationContextElement()` pattern performed
outside of the suspending lambda, which is the typical use case.
Closes gh-35469
Prior to this commit, annotations were not found on parameters in an
overridden method unless the method was public. Specifically, the
search algorithm in AnnotatedMethod did not consider a protected or
package-private method in a superclass to be a potential override
candidate. This affects parameter annotation searches in
spring-messaging, spring-webmvc, spring-webflux, and any other
components that use or extend AnnotatedMethod.
To address that, this commit revises the search algorithm in
AnnotatedMethod to consider all non-final declared methods as potential
override candidates, thereby aligning with the search logic in
AnnotationsScanner for the MergedAnnotations API.
Closes gh-35349
Prior to this commit, the Micrometer context-propagation project would
help propagating information from `ThreadLocal`, Reactor `Context` and
other context objects. This is already well supported for Micrometer
Observations.
In the case of Kotlin suspending functions, the processing of tasks
would not necessarily update the `ThreadLocal` when the function is
scheduled on a different thread.
This commit introduces the `PropagationContextElement` operator that
connects the `ThreadLocal`, Reactor `Context` and Coroutine `Context`
for all libraries using the "context-propagation" project.
Applications must manually use this operator in suspending functions
like so:
```
suspend fun suspendingFunction() {
return withContext(PropagationContextElement(currentCoroutineContext())) {
logger.info("Suspending function with traceId")
}
}
```
Closes gh-35185
Prior to this commit, a RetryException thrown for an
InterruptedException returned the wrong value from getRetryCount().
Specifically, the count was one more than it should have been, since the
suppressed exception list contains the initial exception as well as all
retry attempt exceptions.
To address that, this commit introduces an internal
RetryInterruptedException which accounts for this off-by-one error.
Closes gh-35434
In RetryTemplate, if we encounter an InterruptedException while
sleeping for the configured back-off duration, we throw a
RetryException with the InterruptedException as the cause.
However, prior to this commit, that RetryException propagated to the
caller without notifying the registered RetryListener.
To address that, this commit introduces a new
onRetryPolicyInterruption() callback in RetryListener as a companion to
the existing onRetryPolicyExhaustion() callback.
Closes gh-35442
In RetryTemplate, if we encounter an InterruptedException while
sleeping for the configured back-off duration, we throw a
RetryException with the InterruptedException as the cause.
However, in contrast to the specification for RetryException, we do not
currently include the exceptions for previous retry attempts as
suppressed exceptions in the RetryException which is thrown in such
scenarios.
In order to comply with the documented contract for RetryException,
this commit includes exceptions for previous attempts in the
RetryException thrown for an InterruptedException as well.
Closes gh-35434
Prior to this commit, we included the initial exception in the log
message for the initial invocation of a retryable operation; however,
we did not include the current exception in the log message for
subsequent attempts.
For consistency, we now include the current exception in log messages
for subsequent retry attempts as well.
Closes gh-35433
Prior to this commit, gh-32097 added native support for Jetty for both
client and server integrations. The `JettyDataBufferFactory` was
promoted as a first class citizen, extracted from a private class in the
client support. To accomodate with server-side requirements, an extra
`buffer.retain()` call was performed.
While this is useful for server-side support, this introduced a bug in
the data buffer factory, as wrapping an existing chunk means that this
chunk is already retained.
This commit fixes the buffer factory implementation and moved existing
tests from mocks to actual pooled buffer implementations from Jetty.
The extra `buffer.retain()` is now done from the server support, right
before wrapping the buffer.
Fixes gh-35319
As of gh-33616, Spring now supports metadata reading with the ClassFile
API on JDK 24+ runtimes. This commit fixes a bug where
`ArrayStoreException` were thrown when reading annotation attribute
values for arrays.
Fixes gh-35252
This commit mames `StartupStep` extend `AutoCloseable` in order to allow
the try/with resources syntax and making the `step.end()` call
transparent.
Closes gh-35277
Prior to this commit, the MergedAnnotations support (specifically
AnnotationsScanner) and AnnotatedMethod did not find annotations on
overridden methods in type hierarchies with unresolved generics.
The reason for this is that ResolvableType.resolve() returns null for
such an unresolved type, which prevents the search algorithms from
considering such methods as override candidates.
For example, given the following type hierarchy, the compiler does not
generate a method corresponding to processOneAndTwo(Long, String) for
GenericInterfaceImpl. Nonetheless, one would expect an invocation of
processOneAndTwo(Long, String) to be @Transactional since it is
effectively an invocation of processOneAndTwo(Long, C) in
GenericAbstractSuperclass, which overrides/implements
processOneAndTwo(A, B) in GenericInterface, which is annotated with
@Transactional.
However, the MergedAnnotations infrastructure currently does not
determine that processOneAndTwo(Long, C) is @Transactional since it is
not able to determine that processOneAndTwo(Long, C) overrides
processOneAndTwo(A, B) because of the unresolved generic C.
interface GenericInterface<A, B> {
@Transactional
void processOneAndTwo(A value1, B value2);
}
abstract class GenericAbstractSuperclass<C> implements GenericInterface<Long, C> {
@Override
public void processOneAndTwo(Long value1, C value2) {
}
}
static GenericInterfaceImpl extends GenericAbstractSuperclass<String> {
}
To address such issues, this commit changes the logic in
AnnotationsScanner.hasSameGenericTypeParameters() and
AnnotatedMethod.isOverrideFor() so that they use
ResolvableType.toClass() instead of ResolvableType.resolve(). The
former returns Object.class for an unresolved generic which in turn
allows the search algorithms to properly detect method overrides in
such type hierarchies.
Closes gh-35342
Prior to this commit, RetryTemplate supplied the wrong exception to
RetryListener.onRetryPolicyExhaustion(). Specifically, the execute()
method in RetryTemplate supplied the final, composite RetryException to
onRetryPolicyExhaustion() instead of the last exception thrown by the
Retryable operation.
This commit fixes that bug by ensuring that the last exception thrown by
the Retryable operation is supplied to onRetryPolicyExhaustion().
Closes gh-35334
This commit simplifies RetryException to always require a root cause
and mark it as not nullable. Such exception is the exception thrown by
the retryable operation and should always be available as it explains
why the invocation was a candidate for retrying in the first place.
