Address issues where buffers are allocated (and cached somehow) at or
before subscription, and before explicit demand.
The commit adds tests proving the leaks and fixes. The common thread
for all tests is a "zero demand" subscriber that subscribes but does
not request, and then cancels without consuming anything.

This commit introduces tests that verify that both
CssLinkResourceTransformer implementations properly handle empty url()
functions in CSS files.

Includes deprecation of several AnnotationUtils methods and nullability refinements for passed-in function arguments at the MergedAnnotation API level... also, MergedAnnotation.getType() returns a Class now.

Prior to this commit, if a @ControllerAdvice implemented both
RequestBodyAdvice and ResponseBodyAdvice, it was registered twice in
RequestMappingHandlerAdapter.
This commit ensures that such instances are only registered once.
Closes gh-22638
Refine `TypeMappedAnnotation.getValueFromMetaAnnotation` to correctly
account for aliases when finding values from meta-annotations. Prior
to this commit, only convention based mappings were considered when
searching for values on meta-annotations. This meant that declared
meta-annotations that used aliases could return the "default value"
rather than the merged value.
Closes gh-22654
This commit introduces the spring-core-coroutines module
in order to avoid referencing Kotlin code from Java one,
which is currently not supported by Eclipse.
During the build, spring-core-coroutines is merged into
spring-core, so this change is expected to have no impact
for end users.
This module contains functions accessible from Java via
the CoroutinesUtils class to adapt Coroutines and Deferred
instances to and from Mono.
See gh-19975
Update the proxy used in `AnnotatedElementUtils.forAnnotations` so
that it returns a cloned array for calls to `getDeclaredAnnotations`
or `getAnnotations`. This matches the behavior of standard JDK
`AnnotatedElement` implementations.
Closes gh-22655
