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.

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.
See gh-29321
Includes corresponding build upgrade to Tomcat 10.1.1 and Undertow 2.3.0
(while retaining runtime compatibility with Tomcat 10.0 and Undertow 2.2)

Prior to this commit, several variants of observation documentation
would share the same name; for example HTTP client observations for both
blocking and reactive clients would have the same name.
While it is required that they have the same metric name for dashboards,
the observation documentation names should be different so that they can
be documented without confusing developers.
This commit renames the observation documentation names to avoid that.
Closes gh-29431
This commit fixes the observation instrumentation for the reactive HTTP
server by setting the best matching pattern determined by the web
framework into the `ServerRequestObservationContext`.
This information is required by the observation convention for creating
the expected `KeyValue` for the matching pattern. Prior to this commit,
the information was missing and resulted in an UNKNOWN key value.
Fixes gh-29422
Prior to this commit, the ServerHttpObservationFilter would not add
the current observation as a key in the Reactor context, preventing
from being used or propagated during the HTTP exchange handling.
Also, the client instrumentation in `DefaultWebClient` would start
the observation once the request is fully formed and immutable,
preventing the context from being propagated through HTTP request
headers.
This commit fixes both uses cases now by:
* adding the current observation as a key in the reactor context
on the server side
* using the `ClientRequest.Builder` as a Carrier on the client side
Closes gh-29388
This commit ensures that the ConsumesRequestCondition and
ProducesRequestCondition use a case insensitive check when comparing
parameters.
