Prior to this commit, UndertowHeadersAdapter's remove() method violated
the java.util.Map contract by always returning null.
This commit fixes this by returning the previous list stored under the
specified key, and otherwise returning null if no previous value was
present.

No need to log the full exception for a resolved exception, and as the
comment suggests that it mirrors Spring MVC equivalent, which also
logs the message only.
PR gh-24470 introduced a regression for Android users by no longer
escaping closing curly braces in regular expressions.
This commit therefore partially reverts the changes made in 273812f9c5
for closing curly braces (`}`).

Prior to this commit, the hasContributors() method incorrectly returned
false if contributors had been configured.
This commit fixes the logic in hasContributors() and documents it.
Closes#27271
Prior to this commit, if a PathContainer was created using
Options.MESSAGE_ROUTE, DefaultPathSegment#parameters() returned a
mutable map which would allow the user to modify the contents of the
static, shared EMPTY_PARAMS map in DefaultPathContainer.
This commit prevents corruption of the shared EMPTY_PARAMS map by
ensuring that parameters stored in DefaultPathSegment are always
immutable.
Closes gh-27064
This commit makes sure that Synchronoss uses a random temporary
directory to store uploaded files, so that two instances do not collide.
Closes gh-26931
Prior to this commit, when Web MVC attempted to resolve a constructor
argument for a data class constructor with @ModelAttribute binding,
ModelAttributeMethodProcessor failed to unwrap the array returned by
WebRequest.getParameter(String).
According to the Javadoc for WebRequest.getParameter(String), "a
single-value parameter will be exposed as an array with a single
element."
This commit fixes this issue by extracting the single value from such
an array and using that as the constructor argument (potentially
converted by the WebDataBinder).
Closes gh-25200
Prior to this commit, the `NettyHeadersAdapter` would directly delegate
the `add()` and `set()` calls to the adapted
`io.netty.handler.codec.http.HttpHeaders`. This implementation rejects
`null` values with exceptions.
This commit aligns the behavior here with other implementations, by not
rejecting null values but simply ignoring them.
Fixes gh-26277
(cherry-picked from commit 83c19cd60e)
Prior to this commit, a change introduced in gh-25910 would close the
`JsonGenerator` after it's been used for JSON serialization. This would
not only close it and recycle resources, but also flush the underlyning
buffer to the output.
In a case where the JSON serialization process would throw an exception,
the buffer would be still flushed to the response output. Before the
change introduced in gh-25910, the response body could be still empty at
that point and error handling could write an error body instead.
This commits only closes the `JsonGenerator` when serialization has been
successful.
Note that we're changing this in the spirit of backwards compatibility
in the 5.2.x line, but change this won't be merged forward on the 5.3.x
line, for several reasons:
* this behavior is not consistent. If the JSON output exceeds a
certain size, or if Jackson has been configured to flush after each
write, the response output might still contain an incomplete JSON
payload (just like before this change)
* this behavior is not consistent with the WebFlux and Messaging codecs,
which are flushing or closing the generator
* not closing the generator for error cases prevents resources from
being recycled as expected by Jackson
Fixes gh-26246
The migration from JUnit 4 assertions to AssertJ assertions resulted in
several unnecessary casts from int to long that actually cause
assertions to pass when they should otherwise fail.
This commit fixes all such bugs for the pattern `.isNotEqualTo((long)`.
Prior to this commit, references to `JsonGenerator` and
`ByteArrayBuilder` were not closed/released within codecs calls.
This prevents Jackson from reusing more efficiently shared memory
resources.
This commit properly closes/releases Jackson resources in Spring MVC,
Spring WebFlux and Spring Messaging codecs.
A benchmark on WebFlux codecs (in both single value/streaming mode)
shows significant throughput and allocation improvements for small
payloads.
