This commit replaces uses of onErrorResume() with
- onErrorMap() in places where onErrorResume() is just used to map to a
different exception.
- onErrorComplete() where onErrorResume() just maps to Mono.empty().
- onErrorReturn() where onErrorResum() just maps to Mono.just().
Closes gh-31352
This commit deprecates the various nullSafeHashCode methods taking array
types as they are superseded by Arrays.hashCode now. This means that
the now only remaining nullSafeHashCode method does not trigger a
warning only if the target type is not an array. At the same time, there
are multiple use of this method on several elements, handling the
accumulation of hash codes.
For that reason, this commit also introduces a nullSafeHash that takes
an array of elements. The only difference between Objects.hash is that
this method handles arrays.
The codebase has been reviewed to use any of those two methods when it
is possible.

This commit changes the way request attributes are handled in
RequestPredicates. Previously, the AND/OR/NOT predicates copied all
attributes in a map, and restored that when the delegate predicate(s)
failed.
Now, we only set the attributes when all delegates have succeeded.
Closes gh-30028
This commit refines CORS wildcard processing Javadoc to
provides more details on how wildcards are handled for
Access-Control-Allow-Methods, Access-Control-Allow-Headers
and Access-Control-Expose-Headers CORS headers.
For Access-Control-Expose-Headers, it is not possible to copy
the response headers which are not available at the point
when the CorsProcessor is invoked. Since all the major browsers
seem to support wildcard including on requests with credentials,
and since this is ultimately the user-agent responsibility to
check on client-side what is authorized or not, Spring Framework
continues to support this use case.

This commit schedules blocking I/O operations on the bounded elastic
scheduler, which includes retrieving the content length and writing
the resource (region).
