We now look for the target exception types in cause chain as well,
but return false if we encounter a RestClient or WebClient
exception in the chain.

Prior to this commit, the HTTP interface client would create URI
templates and name query params like so:
"?{queryParam0}={queryParam0[0]}".
While technically correct, the URI template is further used in
observations as a KeyValue. This means that several service methods
could result in having the exact same URI template even if they produce
a different set of query params.
This commit improves the naming of query params in the generated URI
templates for better observability integration.
Closes gh-34176
This change ensures that a request containing query parameters in the
array format `someArray[]=value` can be bound into a simple array in
constructors, even for cases where the array values don't have nested
properties.
The value resolver is directly called in the constructor case, before
any mutable properties are considered or even cleared (see
`WebDataBinder#adaptEmptyArrayIndices` method). As a result, we need to
accommodate the possibility that the request stores array elements under
the `name[]` key rather than `name`. This change attempts a secondary
lookup with the `[]` suffix if the type is a list or array, and the key
doesn't include an index.
Closes gh-34121
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
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
Prior to this commit, the `DefaultServerRequestObservationConvention`
for Servlet failed when the HTTP response status was invalid (for
example, set to "0").
This commit catches `IllegalArgumentException` thrown for such invalid
HTTP status and instead returns an unknown outcome for the observation.
Fixes gh-33725
Prior to this commit, the Jackson2 decoders (JSON, Smile, CBOR) could
leak buffers in case the decoding operation times out or is cancelled
and some buffers are still in flight.
This commit ensures that buffers are released on cancel signals.
Fixes gh-33731
