Prior to this commit, the `ServerHttpObservationFilter` was fixed to
re-enable instrumentation for async dispatches. This fix involves using
an AsyncListener to be notified of exchange completion.
This change was incomplete, as this would not work in some cases.
If another filter starts the async mode and initiates an ASYNC dispatch,
before async handling at the controller level, the async listener is not
registered against subsequent async starts.
This commit not only ensures that the async listener registers
against new async starts, but also ensure that the initial creation and
registration only happens during the initial REQUEST dispatch.
Fixes gh-33451
This commit updates the Evaluation chapter to reflect the following.
- SimpleEvaluationContext no longer has a create() method. Instead it
has forPropertyAccessors(), forReadOnlyDataBinding(), and
forReadWriteDataBinding() factory methods.
- SpEL cannot automatically create missing array elements or grow the
size of an array like it can for a collection.
Closes gh-33456
Prior to this commit, the main() method attempted to retrieve a
TransferService bean from the context, but no such bean had been
configured in the context.
This commit addresses that by configuring a TransferService bean in the
context.
Closes gh-33446
Prior to this commit, the `RestClient` instrumentation would create and
close observations for HTTP requests, but would not open an observation
scope for the lifetime of the exchange.
This means that custom `ClientHttpRequestInterceptor` and
`ResponseErrorHandler` would not get access to the current observation
scope in case of tracing, possibly leading to missing trace ids in logs.
This commit ensures that an observation scope is managed for the
lifetime of the HTTP exchange.
Fixes gh-33397
This commit applies the same kind of processing for
Void.class element type in the ParameterizedTypeReference
variant of WebTestClient.ResponseSpec#returnResult than
in the Class variant.
Closes gh-33389
Prior to this commit if the return type is a CompletableFuture but a
cache get returns null, the execution falls through to the
reactiveCachingHandler.
This commit ensures that evaluation instead continues onto the next
cache (if any).

This commit revises QualifierAnnotationAutowireCandidateResolver to
reinstate "qualifier" support for the legacy JSR-330
@javax.inject.Named annotation.
See gh-31090
Closes gh-33345
When ScheduledAnnotationReactiveSupport adds the Observation to the
context, Reactor opens a scope through the Context Propagation API.
This happens before TrackingSubscriber would start the Observation and
opening a scope without starting an Observation is invalid.
This change moves the Observation start before the scope opening.
Closes gh-33349
Before UnknownContentTypeException is thrown, it is added to the current
Observation but since UnknownContentTypeException is a
RestClientException, the exception is added again in one of the
catch blocks later on.
Closes gh-33347
