Previously, SingletonSupplier stored "null" in singletonInstance when
the supplied instance was "null". On subsequent get() calls, this was
treated as "uninitialized" and triggered another attempt to obtain an
instance from the Supplier.
This commit ensures that a "null" returned from the instanceSupplier or
defaultSupplier is handled correctly, so that subsequent calls to get()
return "null" consistently instead of repeatedly invoking the Supplier.

Prior to this commit, getPubliclyAccessibleMethodIfPossible() in
ClassUtils incorrectly returned a hidden static method as an
"equivalent" method for a static method with the same signature;
however, a static method cannot be overridden and therefore has no
"equivalent" method in a super type.
To fix that bug, this commit immediately aborts the search for an
"equivalent" publicly accessible method when the original method is a
static method.

As reported in gh-34651, `DataBuffer#getByte` can be inefficient for
some implementations, as bound checks are performed for each call.
This commit introduces a new `forEachByte` method that helps with
traversing operations without paying the bound check cost for each byte.
Closes gh-35623
Prior to this commit, our @Retryable support as well as a RetryPolicy
created by the RetryPolicy.Builder only matched against top-level
exceptions when filtering included/excluded exceptions thrown by a
@Retryable method or Retryable operation.
With this commit, we now match against not only top-level exceptions
but also nested causes within those top-level exceptions. This is
achieved via the new ExceptionTypeFilter.match(Throwable, boolean)
support.
See gh-35592
Closes gh-35583
Prior to this commit, ExceptionTypeFilter only provided support for
filtering based on exact matches against exception types; however, some
use cases require that filtering be applied to nested causes in a given
exception. For example, this functionality is a prerequisite for
gh-35583.
This commit introduces a new match(Throwable, boolean) method in
ExceptionTypeFilter, where the boolean flag enables matching against
nested exceptions.

SingletonSupplier<T> supplier-based static methods nullability should
be refined to accept in a flexible way nullable or non-nullable T.
Closes gh-35559
This commit reinstantiates checks for kotlin-reflect (via static final
fields for faster Java code paths and better native code removal) which
were removed as part of gh-34275, which did not consider the
increasingly popular use cases where kotlin-stdlib is present in the
classpath as a transitive dependency in Java applications.
Closes gh-35511
