Prior to this commit, parallel invocations of
MethodParameter.findParameterIndex() (invoked indirectly via
SynthesizingMethodParameter.forParameter() and
MethodParameter.forParameter()) could intermittently lead to an
IllegalArgumentException being thrown due to a race condition in the
internal implementation of the JDK's
java.lang.reflect.Executable.getParameters() method.
This commit addresses this issue by introducing a fallback for-loop
that iterates over the candidate parameters a second time using
equality checks instead of identity checks.
Issue: SPR-17534
(cherry-picked from commit 81fde5ec4103e3db28bf79073691938a4743b121)
As discussed in KT-25165, from a Kotlin POV enum constructors
have no parameter, this is an "implementation detail"
required for running on the JVM, so it seems relevant to skip
Kotlin reflection in that case and just delegate to Java
reflection.
Issue: SPR-16931
This commit makes sure that in DataBufferUtils.write, any received data

Issue: SPR-16782
(cherry picked from commit 1a0522b8057dead47c90404d629c7597d0787dce)

Issue: SPR-17025
(cherry picked from commit 196c0adf47868467ec9242daea81ce7e0246a152)
Before this commit, Kotlin inner class nested configuration
handling thrown an IndexOutOfBoundsException due to bogus filtering
of its constructor parameter reference to an instance of the outer
class.
This commit keep constructor parameter of type INSTANCE in order to
throw a more meaningful NoSuchBeanDefinitionException.
