Also fix a couple of related issues:
- add AsyncRequestNotUsableException to the list of exceptions
that imply response issues.
- handle exceptions from @ExceptionHandler regardless of whether
thrown immediately or via Publisher.
Closes gh-32359
The following adjustments are also made as a result:
- Use int to check if lock is held and unlock is needed, given that
for non-async requests we don't need to obtain a lock.
- Protect access methods getOutputStream and getWriter with the
same locking and state checks.

This commit updates ServletServerHttpResponse.ServletResponseHttpHeaders
in order to use ServletResponse#getContentType instead of
ServletResponse#getHeader.
It allows to have a consistent behavior between Tomcat (which sets only
the former) and Undertow/Jetty (which set both).
Closes gh-32339
ServletResponseHttpHeaders#get should be annotated with `@Nullable` and
return null instead of a singleton list containing null when there is no
content type header.
Closes gh-32362
In addition to using the ServletOutputStream, it's also possible to call
ServletResponse#flushBuffer, so the ServletOutputStream wrapper logic needs
to apply there as well.
See gh-32340
The wrapped response prevents use after AsyncListener onError or completion
to ensure compliance with Servlet Spec 2.3.3.4.
The wrapped response is applied in RequestMappingHandlerAdapter.
The wrapped response raises AsyncRequestNotUsableException that is now
handled in DefaultHandlerExceptionResolver.

This commit refines WebMVC and WebFlux argument resolution in order to
convert properly Kotlin value class arguments by using the type of the
value instead of the type of the value class.
Closes gh-32353
The HttpHeaders.getAcceptLanguageAsLocales was incurring overhead from
using a Stream, as well as calling the fairly expensive
Locale.getDisplayName method.
Switch to using an ArrayList, and skipping over wildcard ranges to avoid
needing to check the display name.
Closes gh-32318
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
Based on feedback from several members of the community, we have
decided to revert the caching of the Content-Type header that was
introduced in ContentCachingResponseWrapper in 375e0e6827.
This commit therefore completely removes Content-Type caching in
ContentCachingResponseWrapper and updates the existing tests
accordingly.
To provide guards against future regressions in this area, this commit
also introduces explicit tests for the 6 ways to set the content length
in ContentCachingResponseWrapper and modifies a test in
ShallowEtagHeaderFilterTests to ensure that a Content-Type header set
directly on ContentCachingResponseWrapper is propagated to the
underlying response even if content caching is disabled for the
ShallowEtagHeaderFilter.
See gh-32039
Closes gh-32317
Prior to this commit, getHeaderNames() returned duplicates for the
Content-Type and Content-Length headers if they were set in the wrapped
response as well as in ContentCachingResponseWrapper.
This commit fixes that by returning a unique set from getHeaderNames().
In addition, this commit introduces a new test in
ContentCachingResponseWrapperTests to verify the expected behavior for
Content-Type and Content-Length headers that are set in the wrapped
response as well as in ContentCachingResponseWrapper.
See gh-32039
See gh-32317
Commit 375e0e6827 introduced a regression in
ContentCachingResponseWrapper (CCRW). Specifically, CCRW no longer
honors Content-Type and Content-Length headers that have been set on
the wrapped response and returns null for those header values if they
have not been set directly on the CCRW.
This commit fixes this regression as follows.
- The Content-Type and Content-Length headers set in the wrapped
response are honored in getContentType(), containsHeader(),
getHeader(), and getHeaders() unless those headers have been set
directly on the CCRW.
- In copyBodyToResponse(), the Content-Type in the wrapped response is
only overridden if the Content-Type has been set directly on the CCRW.
See gh-32039
Closes gh-32317
