This commit reorders and clarifies the usage instructions for
ApplicationEvents to:
1. Recommend method parameter injection as the primary approach, since
ApplicationEvents has a per-method lifecycle
2. Clarify that ApplicationEvents is not a general Spring bean and
cannot be constructor-injected
3. Explicitly state that field injection is an alternative approach
This addresses confusion where developers expect ApplicationEvents to
behave like a regular Spring bean eligible for constructor injection.

that follows the OpenTelemetry semantic convention for HTTP Server
metrics and spans.

Undertow does not support Servlet 6.1, we need to remove compatibility
tests as well as Undertow-specific classes for WebSocket and reactive

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.

Prior to this commit, a regexp path segment ending with a double wilcard
(like "/path**") would be incorrectly parsed as a double wildcard
segment ("/**").
This commit fixes the incorrect parsing.
Fixes gh-35339
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.
