This commit refines Coroutines annotated controller support
by considering Kotlin Unit as Java void and using the right
ReactiveAdapter to support all use cases, including suspending
functions that return Flow (usual when using APIs like WebClient).
It also fixes RSocket fire and forget handling and adds related tests
for that use case.

Before this commit the connector waited for a completed response (via
ServerHttpResponse#setComplete or ServerHttpResponse#writeWith) or an
error signal in handling, but it didn't deal explicitly with the case
where both can occur.
This commit explicitly waits for the completion of handling (success
or error) before passing the response downstream. If an error occurs
after response completion, it is wrapped in a dedicated exception that
also provides access to the completed response.

This commit allows single-value async producers for the values of
metadata entries in both the SETUP and for requests. The same is also
enabled for data in the SETUP frame.

Prior to this commit, methods in a @ControllerAdvice bean were
registered and invoked twice if the advice was a scoped bean (e.g.,
request or session scoped). In other words, both the proxy bean and the
target bean were wrapped in ControllerAdviceBean instances.
This commit fixes this bug by modifying the findAnnotatedBeans() method
in ControllerAdviceBean so that it filters out targets of scoped
proxies.
Closes gh-24017
Spring Framework 5.2 introduced support for implementing the Ordered
interface in a @ControllerAdvice bean. This support requires that
@ControllerAdvice beans be eagerly resolved from the BeanFactory in
order to invoke the getOrder() method defined in the Ordered interface.
Unfortunately doing so resulted in a regression in that an attempt to
eagerly resolve a scoped @ControllerAdvice bean throws a
BeanCreationException due to the lack of an active scope (e.g., request
or session scope).
This commit fixes this regression by avoiding eager resolution of scoped
@ControllerAdvice beans. As a direct consequence, the Ordered interface
is not supported for scoped @ControllerAdvice beans.
Closes gh-23985
Before this change an @MessageMapping could be matched to any RSocket
interaction type, which is arguably too flexible, makes it difficult to
reason what would happen in case of a significant mismatch of
cardinality, e.g. request for Fire-And-Forget (1-to-0) mapped to a
method that returns Flux, and could result in payloads being ignored,
or not seen unintentionally.
This commit checks @ConnectMapping method on startup and rejects them
if they return any values (sync or async). It also refines each
@MessageMapping to match only the RSocket interaction type it fits
based on the input and output cardinality of the handler method.
Subsequently if a request is not matched, we'll do a second search to
identify partial matches (by route only) and raise a helpful error that
explains which interaction type is actually supported.
The reference docs has been updated to explain the options.
Closes gh-23999
This commit adds support for Continuation parameter that is now
considered as an optional parameter since it is never provided by
the user.
It also simplifies and optimizes the implementation.
