Since Spring Framework 6 uses JDK 17 for its baseline, we can make use
of toList() and toUnmodifiableSet() which were introduced in JDK 16 and
JDK 10, respectively.
Closes gh-27618
This commit introduces UnmodifiableMultiValueMap, an immutable wrapper
around a MultiValueMap, similar to what is returned by
Collections.unmodifiable*.
CollectionUtils::unmodifiableMultiValueMap now returns
UnmodifiableMultiValueMap.
Closes gh-27608
The fix made for gh-27488 resulted in a change of the default order
of codecs. This commit reverts these changes, so that the previous
order is restored.
Closes gh-27573
This commit also applies additional clean-up tasks such as the following.
- final fields
- diamond operator (<>) for anonymous inner classes
This has only been applied to `src/main/java`.
This commit makes sure that the Reactor context from a given mono or
flux is propagated to the Flux returned by a FluxSink. This change
affects both DataBufferUtils::write and internal classes used by the
DefaultPartHttpMessageReader.
Closes gh-27517
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 (`}`).
Closes gh27467
Previous to this commit, the specificity and quality comparators
(used by MediaType::sortByQualityValue and MediaType::sortBySpecificity)
could result in IllegalArgumentExceptions when used for sorting.
The underlying reason was that the comparators were not transitive, and
both media types with the same type, and types with the same amount of
parameters, would be considered identical by the comparator (result 0).
This commit ensures that the comparators are transitive.
Closes gh-27488
In order to catch Javadoc errors in the build, we now enable the
`Xwerror` flag for the `javadoc` tool. In addition, we now use
`Xdoclint:syntax` instead of `Xdoclint:none` in order to validate
syntax within our Javadoc.
This commit fixes all resulting Javadoc errors and warnings.
This commit also upgrades to Undertow 2.2.12.Final and fixes the
artifact names for exclusions for the Servlet and annotations APIs.
The incorrect exclusion of the Servlet API resulted in the Servlet API
being on the classpath twice for the javadoc task, which resulted in the
following warnings in previous builds.
javadoc: warning - Multiple sources of package comments found for package "javax.servlet"
javadoc: warning - Multiple sources of package comments found for package "javax.servlet.http"
javadoc: warning - Multiple sources of package comments found for package "javax.servlet.descriptor"
javadoc: warning - Multiple sources of package comments found for package "javax.servlet.annotation"
Closes gh-27480
In order to be able to use text blocks and other new Java language
features, we are upgrading to a recent version of Checkstyle.
The latest version of spring-javaformat-checkstyle (0.0.28) is built
against Checkstyle 8.32 which does not include support for language
features such as text blocks. Support for text blocks was added in
Checkstyle 8.36.
In addition, there is a binary compatibility issue between
spring-javaformat-checkstyle 0.0.28 and Checkstyle 8.42. Thus we cannot
use Checkstyle 8.42 or higher.
In this commit, we therefore upgrade to spring-javaformat-checkstyle
0.0.28 and downgrade to Checkstyle 8.41.
This change is being applied to `5.3.x` as well as `main` in order to
benefit from the enhanced checking provided in more recent versions of
Checkstyle.
Closes gh-27481
Prior to this commit, calling `StringUtils#collectionToDelimitedString`
would fail with an NPE if the collection contains null elements.
This commit ensures that null elements are converted as `"null"` in the
resulting String without failure.
