This commit makes several changes to MimeType and MediaType
related to the topic of specificity.
This commit deprecates the MimeType and MediaType Comparators.
Comparators require a transitive relationship, and the desired order for
these types is not transitive (see #27488).
Instead, this commit introduces two new MimeType methods: isMoreSpecific
and isLessSpecific, both of which return booleans. MediaType overrides
these methods to include the quality factor (q) in the comparison.
All MediaType sorting methods have been deprecated in favor of
MimeTypeUtils::sortBySpecificity. This sorting method now uses
MimeType::isLessSpecific in combination a bubble sort algorithm (which
does not require a transitive compare function).
Closes gh-27580
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
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
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.

Includes hard JDK 9+ API dependency in CGLIB ReflectUtils (Lookup.defineClass) and removal of OutputStream spy proxy usage (avoiding invalid Mockito proxy on JDK 17)
Closes gh-26901
This commit applies several optimizations to StringUtils#cleanPath and
related methods:
* pre-size pathElements deque in StringUtils#cleanPath with
pathElements.length elements, since this this is the maximum size and
the most likely case.
* optimize StringUtils#collectionToDelimitedString to calculate the size
of the resulting String and avoid array auto-resizing in the
StringBuilder.
* If the path did not contain any components that required cleaning,
return the (normalized) path as-is. No need to concatenate the prefix
and the trailing path.
See gh-26316
To slightly improve performance, this commit switches to
StringBuilder.append(char) instead of StringBuilder.append(String)
whenever we append a single character to a StringBuilder.
Closes gh-27098
Prior to this commit, ConfigurationClass implemented equals(),
hashCode(), and toString(), but BeanMethod did not.
This commit introduces equals(), hashCode(), and toString()
implementations in BeanMethod for consistency with ConfigurationClass
to make it possible to use BeanMethod instances to index additional
metadata as well.
In order to properly implement equals() in BeanMethod, the method
argument types are required, but these are not directly available in
BeanMethod. However, they are available via ASM when processing @Bean
methods. This commit therefore implements equals(), hashCode(), and
toString() in SimpleMethodMetadata which BeanMethod delegates to.
For completeness, this commit also implements equals(), hashCode(), and
toString() in StandardClassMetadata, StandardMethodMetadata, and
SimpleAnnotationMetadata.
Closes gh-27076
This commit makes sure that LinkedCaseInsensitiveMap::computeIfAbsent
honors the contract of the method, and also replaces the old entry if
that mapped to null.

Add factory methods to `AbstractEnvironment` that allow a custom
`ConfigurablePropertyResolver` and `MutablePropertySources` instance
to be used.

This commit updates the reference manual to point out that one may use
`.` instead of `$` as the nested class separator when providing a fully
qualified class name for a nested class in XML configuration.
This commit also updates the test for ClassUtils#forName to assert
support for `.` instead of `$`.
Closes gh-26540
This commit makes sure the StringDecoder supports stripping off
multi-line delimiters, such as \r\n. Specifically, we ensure that the
delimiter is stripped from the joined buffer.
Closes gh-26511
This commit introduces computeAttribute() as an interface default method
in the AttributeAccessor API. This serves as a convenience analogous to
the computeIfAbsent() method in java.util.Map.
