This commit ensures that the same multipart codecs are registered on
both client and server. Previously, only the client enabled only sending
multipart, and the server only receiving.
Closes gh-29630
LocalVariableTableParameterNameDiscoverer is not registered by default anymore now.
Java sources should be compiled with `-parameters` instead (available since Java 8).
Also retaining standard Java parameter names for all of Spring's Kotlin sources now.
Closes gh-29531
Prior to this commit, the server observability support would create a
cycle in Java packages.
This commit refactors the current arrangement to solve this by:
* "flattening" the reactive HTTP instrumentation; this removes the
dependency to the `ServerWebExchange` and `PathPattern` types
* moving the `observation` package under
`org.springframework.http.server` and
`org.springframework.http.server.reactive`

Commit #2878ad added the DispatchExceptionHandler contract for
mapping an error before a handler is selected to a HandlerResult.
The same is also convenient for use in HandlerResult itself which
currently uses a java.util.Function essentially for the same.
See gh-22991
This change enables a WebFlux HandlerAdapter to handle not only the
success scenario when a handler is selected, but also any potential
error signal that may occur instead. This makes it possible to
extend ControllerAdvice support to exceptions from handler mapping
such as a 404, 406, 415, and/or even earlier exceptions from the
WebFilter chain.
Closes gh-22991
This commit reverts changes to AbstractCacheManager since iterating
over the caches in a for-loop and a stream is duplicated effort.
This commit reverts changes to DefaultRenderingResponseBuilder,
RouterFunctions, and OriginHandshakeInterceptor since order matters for
those use cases: they were originally based on the semantics of
LinkedHashSet or LinkedHashMap; whereas, Set.copyOf() and Map.copyOf()
do not provide any guarantees regarding ordering.
This commit also applies analogous changes to "sibling" implementations
across Servlet mocks as well as Web MVC and WebFlux.
