Returning a private class from a package-private method causes the
AOT-generated source files to fail to compile as the private class is
not visible.
Closes gh-33106
Update `MeterRegistryPostProcessor` to configure `MeterRegistry` beans
in two distinct sweeps. The first sweep applies customizers and filters
as the `MeterRegistry` bean is initialized, the second sweep applies
`MeterBinder` beans once all singletons have been instantiated.
Prior to this commit, it was not possible for a `MeterBinder` bean to
directly or indirectly use a `MeterRegistry`. It was also possible for
bound meters to cause a deadlock during refresh processing if those
meters could be updated on a thread other than main, such as GC
notifications.
Fixes gh-30636
Fixes gh-33070
Update types returned from endpoints to implement the
`OperationResponseBody` interface. This ensures that they will be
serialized using the isolated actuator `ObjectMapper`.
See gh-20291
Add `OperationResponseBody` tagging interface that can be used
to trigger the use of an isolated ObjectMapper specifically for
actuator responses.
The isolated mapper is provided by an `EndpointObjectMapper`
bean which is auto-configured unless specifically disabled
by the user.
WebMVC, WebFlux and Jersey integrations have been updated
to provide a link between the `OperationResponseBody` type
and the endpoint `ObjectMapper`.
See gh-20291
Rename `/actuator/httptrace` to `/actuator/httpexchanges` to better
describe its purpose and to remove confusion with distribute tracing.
This change also takes the opportunity to improve the code by making
the `HttpExchange` class (previously `HttpTrace`) fully immutable.
Closes gh-32885

Without this change we're missing the BaggageTextMapPropagator for
OTel. This means that we're not propagating remote-fields
(only baggage via the 'baggage' field).
With this change we're adding the missing propagator as
THE LAST entry in the composite TextMapPropagator. It has to be
last cause with the latest Snapshots of Micrometer Tracing it
will append the remote field baggage to existing baggage in the
context extracted via the W3CBaggagePropagator.

Prior to this commit, Spring Boot would offer a specific Metrics
instrumentation for WebFlux applications through a `WebFilter` and
custom Tag providers.
As of Spring Framework 6.0, the Observation instrumentation is done
directly in WebFlux, also with a `WebFilter`. While this allows both
metrics and traces, some features cannot be supported in the same way
with this new infrastructure.
The former `WebFilter` has been removed and the Tagging infrastructure
deprecated in favor of custom Observation conventions. This commit
provides an adapter layer so that developers can refactor their custom
tagging solution to the convention way, during the deprecation phase,
without losing any feature.
Closes gh-32539
This commit migrates the existing metrics support (added in #29140) to
the new `Observation` instrumentation contributed in
spring-projects/spring-graphql#501.
We cannot have a smoother migration path here as the instrumentation
does not use the same context information for metadata extraction.
Closes gh-32794
