The converter now tries to keep reading from the same InputStream which
should be possible with ordered and non-overlapping regions. When
necessary the InputStream is re-opened.

Prior to Spring Framework 5.2, most annotation search algorithms made
use of AnnotationUtils.handleIntrospectionFailure() to handle exceptions
thrown while attempting to introspect annotation metadata. With the
introduction of the new MergedAnnotation API in Spring Framework 5.2,
this exception handling was accidentally removed.
This commit introduces the use of handleIntrospectionFailure() within
the new MergedAnnotation internals in order to (hopefully) align with
the previous behavior.
Closes gh-24188
Prior to this commit, when searching for annotations using the
TYPE_HIERARCHY_AND_ENCLOSING_CLASSES strategy an exception could be
thrown while attempting to load the enclosing class (e.g., a
NoClassDefFoundError), thereby halting the entire annotation scanning
process.
This commit makes this search strategy defensive by logging exceptions
encountered while processing the enclosing class hierarchy instead of
allowing the exception to halt the entire annotation scanning process.
The exception handling is performed by
AnnotationUtils.handleIntrospectionFailure() which only allows an
AnnotationConfigurationException to propagate.
See gh-24136
Prior to this commit, the enclosing class was always eagerly loaded
even if the annotation search strategy was not explicitly
TYPE_HIERARCHY_AND_ENCLOSING_CLASSES.

Given the following improperly configured composed @RequestMapping
annotation:
@Retention(RetentionPolicy.RUNTIME)
@RequestMapping
@interface PostApi {
@AliasFor("value")
String[] path() default {};
@AliasFor(annotation = RequestMapping.class, attribute = "path")
String[] value() default {};
}
Prior to this commit, an attempt to process the above annotation
resulted in an exception similar to the following, which is not
especially helpful to discern the problem.
> Attribute 'value' in annotation [PostApi] must be declared as an
> @AliasFor 'path', not 'path'.
This commit improves the exception message for such scenarios,
resulting in an exception message similar to the following.
> Attribute 'value' in annotation [PostApi] must be declared as an
> @AliasFor attribute 'path' in annotation [PostApi], not attribute
> 'path' in annotation [RequestMapping].
Closes gh-24168
Update `ResolvableType` so that variable referenced can be resolved
against wildcard types. Prior to this commit, given a type:
Map<String, ? extends List<? extends CharSequence>>
Calling `type.getGeneric(1).asCollection().resolveGeneric()` would
return `null`. This was because the `List` variable `E` referenced a
wildcard type which `resolveVariable` did not support.
Closes gh-24145
Spring Framework 5.2 introduced a regression for implicit aliases
declared via @AliasFor. Specifically, Spring's merged annotation
algorithms stopped honoring default values for implicit alias pairs if
the composed annotation was used without specifying the aliased
attributes.
This commit fixes this regression.
Closes gh-24110
Spring Framework 5.2 introduced a regression in reflection-based
AnnotationMetadata. Specifically, as of 5.2, StandardAnnotationMetadata
no longer found @Inherited annotations from superclasses.
This commit fixes this regression by switching to the INHERITED_ANNOTATIONS
SearchStrategy when creating the MergedAnnotations used within
StandardAnnotationMetadata,
Note, however, that the discrepancy between StandardAnnotationMetadata
and SimpleAnnotationMetadata (i.e., reflection-based vs. ASM-based)
regarding @Inherited support still remains as it was prior to Spring
Framework 5.2.
Closes gh-24077
This commit introduces failing assertions that are currently disabled
via a boolean reproduceGh24077 flag.
Setting that flag to true demonstrates the regression for
StandardAnnotationMetadata and inconsistencies for SimpleAnnotationMetadata.

This commit refines Coroutines annotated controller support
by considering Kotlin Unit as Java void and using the right
ReactiveAdapter to support all use cases, including suspending
functions that return Flow (usual when using APIs like WebClient).
It also fixes RSocket fire and forget handling and adds related tests
for that use case.
Closes gh-24057
Closes gh-23866
This commit adds support for Continuation parameter that is now
considered as an optional parameter since it is never provided by
the user.
It also simplifies and optimizes the implementation.
Closes gh-23991
Prior to this commit, the TestGroup.CI enum constant was only used in a
single test method in spring-core. In order to enable that test, the
`testGroups` JVM system property was configured for the
Publication-master CI build plan; however, the `testGroups` system
property is not set when executing local builds. Consequently, there
has been a Gradle cache miss for every `test` task when building
something locally that's already been built on the CI server.
This commit addresses this issue by removing the `TestGroup.CI` enum
constant. The `-PtestGroups=ci` command line configuration for the
Publication-master CI build plan has also been removed on the CI server.
Closes gh-23918
