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"

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.

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.

Migrate `CoroutinesUtils` from Kotlin code to Java and drop the
`kotlin-coroutines` module.
This update removes the need for Kotlin tooling IDE plugins to be
installed.
Closes gh-27379
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
Prior to this commit, the toString() implementation did not separate
method argument types with a comma or any form of separator, leading
to results such as:
org.example.MyClass.myMethod(java.lang.Stringjava.lang.Integer)
instead of:
org.example.MyClass.myMethod(java.lang.String,java.lang.Integer)
Closes gh-27095
Proposed change aimed to keep coherence between variable declaration
and static initialization code, which stores 9 values, not 8, in these
two maps.
Closes gh-27016
Prior to this commit, in some cases application context startup steps
could be created concurrently, which could cause issues with the current
implementation tracking the parent/child relationship between steps.
This commit ensures that the flight recorder implementation is using
thread safe collection implementations for that.

This commit makes sure that LinkedCaseInsensitiveMap::computeIfAbsent
honors the contract of the method, and also replaces the old entry if
that mapped to null.

Class.getResource, ClassLoader.getResource, and ClassLoader.getSystemResource will throw IllegalArgumentException if a malformed URL is provided to them.
According to its javadoc, resolveURL should return null if not resolvable, so catch the IllegalArgumentException and return null.
Add factory methods to `AbstractEnvironment` that allow a custom
`ConfigurablePropertyResolver` and `MutablePropertySources` instance
to be used.

With the introduction of the -H:+InlineBeforeAnalysis native image
compiler flag in GraalVM 21.0.0, it is now possible to use an utility method and get code
removal at build time.
This flag will be enabled as of Spring Native 0.9.0.

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.
Closes gh-26281
HttpMessageWriter implementations now attach the request log prefix
as a hint to created data buffers when the logger associated with
the writer is at DEBUG level.
Closes gh-26230
The previous implementation uses ArrayList for storing resolved
resources and ArrayList has O(n) time complexity for the contains
operation. By switching to the HashSet for storing resolved
resources we improve the time complexity of this operation to be O(1).
See gh-25927
There are more locations which could benefit from not using a
toCharArray on a String, but rather use the charAt method from
the String itself. This to prevent an additional copy of the
char[] being created.
This commit introduces `and()` default methods in the MethodFilter and
FieldFilter functional interfaces in ReflectionUtils in order to simplify
uses cases that need to compose filter logic.
Closes gh-26063
Prior to this commit, MergedAnnotationCollectors.toAnnotationSet()
created an intermediate ArrayList for storing the results prior to
creating a LinkedHashSet in the finishing step.
Since the creation of the intermediate list is unnecessary, this commit
simplifies the implementation of toAnnotationSet() by using the
Collector.of() factory method that does not accept a `finisher` argument.
The resulting Collector internally uses a `castingIdentity()` function
as the `finisher`.
Closes gh-26031
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)`.
The existing implementation was exposed to very poor performance when matching
with multiple delimiters against a large buffer with many delimiters. In that
case all matchers are invoked many times (as many as the number of delimiters)
even though some of them found no match at all on the first pass.
The revised implementation uses a single index and advances all matchers
together, checking one byte a time, and not letting any one of them search to
the end of the entire buffer on a single pass.
Closes gh-25915
Simplify and optimize the processing of the input stream.
The existing implementation was using bufferUntil and creating a List
for every line along with an EndFrameBuffer inserted for the
bufferUntil predicate. So the larger the input buffer and the more
lines it contained, the greater the overhead.
The new implementation avoids bufferUntil for all lines and
instead uses concatMapIterable to aggregate the lines from a buffer
into a single list. So the larger the input buffer and the more
lines it contains, the better the throughput. The only buffering
used then is for partial chunks and those are accumulated in a list.
See gh-25915
Before this commit, ReadCompletionHandler delayed closing the channel
to allow an ongoing read to complete/fail so we can get a hold of the
associated DataBuffer and release it. This can be problematic since the
read take time to complete but even more importantly there was a race
condition where we didn't check if we've been disposed concurrently
while releasing the read flag.
This commit removes the delay and closes the channel immediately from
cancel() and that should in turn fail any ongoing read operation,
according to AsynchronousChannel, and the DataBuffer is released.
Further improvements include:
- combining the "reading" and "disposed" AtomicBoolean's into a
single "state" AtomicReference.
- an optimistic check to remain in READING mode and avoid state
switches when there is demand to continue reading.
Closes gh-25831
This commit raises the minimum Coroutines version supported

Closes gh-25007
This commit adds support for Kotlin Coroutines suspending functions to
Spring MVC, by converting those to a Mono that can then be handled by
the asynchronous request processing feature.
It also optimizes Coroutines detection with the introduction of an
optimized KotlinDetector.isSuspendingFunction() method that does not
require kotlin-reflect.
