Before this commit, in Spring Framework 6.2, Kotlin value class
unboxing was done at CoroutinesUtils level, which is a good fit
for InvocableHandlerMethod use case, but not for other ones like
AopUtils.
This commit moves such unboxing to InvocableHandlerMethod in
order to keep the HTTP response body support while fixing other
regressions.
Closes gh-33943
Prior to this commit, `RestClient` would not use the full URI created by
the uri handler as a template request attribute.
This means that HTTP client observations would not contain the base URI
in recorded observations as the uri template keyvalue.
Closes gh-33928
This ensures that the reactive handling of the request is dispatched
from the Undertow IO thread, marking the exchange as async rather than
ending it once the Undertow `handleRequest` method returns.
Closes gh-33885
Since Joda-Time support was removed in Spring Framework 6.0, this commit
removes obsolete mentions of Joda-Time in the reference guide and Javadoc.
See gh-27426
Closes gh-33881
Prior to this commit, a client sending a request to
"https://example.org" would record the wrong URI tag as
"/https://example.org".
This commit ensures that the scheme+host part is matched correctly in
the default client observation conventions.
See gh-33867
The `HttpHeaders#headerSet` method is intended as a drop-in replacement
for `entrySet` that guarantees a single casing for all header names
reported during the iteration, as the cost of some overhead but with
support for iterator removal and entry value-setting.
The `formatHeaders` static method is also altered to do a similar
deduplication of casing variants, but now additionally mentions
"with native header names [native name set]" if the native name set
contains casing variants.
Closes gh-33823
Prior to this commit, the `HttpHeaders.writeableHttpHeaders` would only
consider headers read-only instances that were wrapped once by
`HttpHeaders.readOnlyHttpHeaders`. This does not work when other
`HttpHeaders` wrappers are involved in the chain.
This commit ensures that `writeableHttpHeaders` unwraps all headers
instances down to the actual multivalue map and create a new headers
instance out of it.
Fixes gh-33789
