Although the initial report in gh-28015 only covered inconsistencies
for arrays and strings in the toString() implementations for
annotations between the JDK (after Java 9) and Spring, it has since
come to our attention that there was further room for improvement.
This commit therefore addresses the following in toString() output for
synthesized annotations.
- characters are now wrapped in single quotes.
- bytes are now properly formatted as "(byte) 0x##".
- long, float, and double values are now appended with "L", "f", and
"d", respectively. The use of lowercase for "f" and "d" is solely to
align with the choice made by the JDK team.
However, this commit does not address the following issues which we may
choose to address at a later point in time.
- non-ASCII, non-visible, and non-printable characters within a
character or String literal are not escaped.
- formatting for float and double values does not take into account
whether a value is not a number (NaN) or infinite.
Closes gh-28015
Since the introduction of synthesized annotation support in Spring
Framework 4.2 (a.k.a., merged annotations), the toString()
implementation attempted to align with the formatting used by the JDK
itself. However, Class annotation attributes were formatted using
Class#getName in Spring; whereas, the JDK used Class#toString up until
JDK 9.
In addition, JDK 9 introduced new formatting for toString() for
annotations, apparently intended to align with the syntax used in the
source code declaration of the annotation. However, JDK 9+ formats enum
annotation attributes using Enum#toString instead of Enum#name, which
can lead to issues if toString() is overridden in an enum.
This commit updates the formatting used for synthesized annotations by
ensuring that toString() generates a string that is compatible with the
syntax of the originating source code, going beyond the changes made in
JDK 9 by using Enum#name instead of Enum#toString.

Prior to this commit, the USER_DECLARED_METHODS MethodFilter in
ReflectionUtils did not actually filter methods declared in
java.lang.Object as stated in its Javadoc.
Consequently, if ReflectionUtils.doWithMethods was invoked with
USER_DECLARED_METHODS and Object.class as the class to introspect, all
non-bridge non-synthetic methods declared in java.lang.Object were
passed to the supplied MethodCallback, which breaks the contract of
USER_DECLARED_METHODS.
In addition, if USER_DECLARED_METHODS was composed with a custom
MethodFilter using `USER_DECLARED_METHODS.and(<custom MethodFilter>)`,
that composed method filter allowed all non-bridge non-synthetic
methods declared in java.lang.Object to be passed to the supplied
MethodCallback, which also breaks the contract of
USER_DECLARED_METHODS. This behavior resulted in regressions in code
that had previously used USER_DECLARED_METHODS by itself and then began
using USER_DECLARED_METHODS in a composed filter. For example, since
commit c419ea7ba7 ReflectiveAspectJAdvisorFactory has incorrectly
processed methods in java.lang.Object as candidates for advice methods.
This commit fixes this bug and associated regressions by ensuring that
USER_DECLARED_METHODS actually filters methods declared in
java.lang.Object. In addition, ReflectionUtils.doWithMethods now aborts
its search algorithm early if invoked with the USER_DECLARED_METHODS
filter and Object.class as the class to introspect.

Prior to this commit, XmlValidationModeDetector did not properly parse
all categories of comments (described below). When such categories of
comments were encountered XmlValidationModeDetector may have
incorrectly detected that an XML file used a DTD when it used an XSD,
or vice versa.
This commit revises the parsing algorithm in XmlValidationModeDetector
so that multi-line comments and multiple comments on a single line are
properly recognized.
Specifically, with this commit the following categories of comments are
now handled properly.
- Multiple comments on a single line
- Multi-line comment: beginning on one line and then ending on another
line with an additional comment following on that same line.
- Multi-line comment: beginning at the end of XML content on one line
and then spanning multiple lines.
Closes gh-27915
Prior to this commit, the error message generated for a mismatched
number of generics did not include the information about the class in
question.
This commit improves the error message by providing more context,
specifically the result of invoking toGenericString() on the class.
For example, instead of throwing an IllegalArgumentException with the
error message "Mismatched number of generics specified", the error
message would now be "Mismatched number of generics specified for
public abstract interface java.util.Map<K,V>".
Closes gh-27847
Where unfeasible, this commit adds inline comments to explain why
try-with-resources must not be used in certain scenarios. The purpose
of the comments is to avoid accidental conversion to try-with-resources
at a later date.

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.

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.

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 (`}`).

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.

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.
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.

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

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.
