Fix `isAssignable` for `ResolvableType.forRawClass` so that it can be
used with types backed by a `TypeVarible`. Prior to this commit the
rawClass value was used, which wouldn't always work.

Closes gh-23321

Prior to this commit, AbstractAutowireCapableBeanFactory's
invokeCustomInitMethod() method invoked
ClassUtils.getInterfaceMethodIfPossible() even if the security manager
was not being used.

This commit ensures that getInterfaceMethodIfPossible() is only invoked
if the security manager is used.

Closes gh-23323

Replace docs on using MultipartBodyBuilder for the RestTemplate with
examples that show MultiValueMap. Originally the idea was to make
MultipartBodyBuilder accessible to the RestTemplate too, but with
support for async parts that's no longer a good fit.

Prior to this commit, there was some ambiguity surrounding semantics
for @Autowired constructors and `required = true`, especially for
multiple @Autowired constructors.

This commit improves the documentation in the Javadoc for @Autowired as
well as in the reference manual.

OncePerRequestFilter now has a doFilter method that allows separate
processing of nested ERROR dispatches. This is useful for filters
that wrap the request and response.

  Fix typo in UrlPathHelper

Fixes gh-23253

Prior to this commit, if the user configured an empty path for the
targetRequestPath property of a FlashMap, the FlashMapManager threw a
StringIndexOutOfBoundsException when saving the output FlashMap for the
next request.

This commit fixes this by skipping the decoding and normalization of an
empty target request path.

Fixes gh-23240

Prior to Spring Framework 5.1.3, MimeTypeUtils.parseMimeTypes() and
MediaType.parseMediaTypes() ignored empty entries, but 5.1.3 introduced
a regression in that an empty entry -- for example, due to a trailing
comma in the list of media types in an HTTP Accept header -- would result
in a "406 Not Acceptable" response status.

This commit fixes this by filtering out empty entries before parsing
them into MimeType and MediaType instances. Empty entries are therefore
effectively ignored.

Use a callback to detect token authentication (via inteceptor) thus
avoiding a potential race between that detection after the message is
sent on the inbound channel (via Executor) and the processing of the
CONNECTED frame returned from the broker on the outbound channel.

Prior to this commit, it was unclear that an invocation of getCache()
might potentially create a new Cache.

This commit updates the Javadoc to point out that concrete CacheManager
implementations may choose to create a new Cache at runtime if the Cache
does not already exist.

This commit clarifies the semantics of the PriorityOrdered interface
with respect to sorting sets of objects containing both PriorityOrdered
and plain Ordered objects.
