Rework AnnotatedElementAdapter to avoid cloning the underlying
Annotation array if it is empty when getAnnotations() is called.
Additionally, make the class static and add a factory method that
returns a singleton instance for null or empty Annotation arrays.
Closes gh-32405
KClass instantiation in CoroutinesUtils is suboptimal, and should be
replaced by KTypes#isSubtypeOf checks using pre-instantiated types for
Flow, Mono and Publisher.
This commit impact on performances is significant since a throughput
increase between 2x and 3x has been measured on basic endpoints.
Closes gh-32390
To smooth upgrade from 6.1.x, this commit makes sure that code that used
to catch an IAE to ignore a faulty placeholder resolution still works.
See gh-9628
This commit fixes a performance regression caused by gh-31698,
and more specifically by KClass#isValue invocations which are slow since
they load the whole module to find the class to get the descriptor.
After discussing with the Kotlin team, it has been decided that only
checking for the presence of `@JvmInline` annotation is enough for
Spring use case.
As a consequence, this commit introduces a new
KotlinDetector#isInlineClass method that performs such check, and
BeanUtils, CoroutinesUtils and WebMVC/WebFlux InvocableHandlerMethod
have been refined to leverage it.
Closes gh-32334
This commit introduces composite collections (i.e. Collection, Set, Map)
and uses these composites in request predicates, where before new
collections were instantiated.
Closes gh-32245
Add helpers to CollectionUtils for building HashSets and LinkedHashSets
that can hold an expected number of elements without needing to
resize/rehash.
Closes gh-32291
In places where a ConcurrentHashMap was used as a set by wrapping it
with Collections.newSetFromMap, switch to just using the set returned
by ConcurrentHashMap.newKeySet directly.
Closes gh-32294
