PR gh-25429 brought it to our attention that there was a bug in
AnnotationScanner when using a non-null class filter that filtered out
classes; however, it turns out that there is no production code that
utilizes the package-private class filtering support.
This commit therefore removes all class filtering support from
AnnotationScanner since that functionality is effectively unused.
Closes gh-25477
Prior to this commit, scanning for annotations resulted in an infinite
loop when using the INHERITED_ANNOTATIONS search strategy and a class
filter that filters out visited classes.
This commit avoids an infinite loop in AnnotationsScanner's
processClassInheritedAnnotations(...) method by skipping the current
level of the class hierarchy when the current source class has been
filtered out.
Closes gh-25429
Prior to this commit, a Profiles instance created via Profiles.of() was
not considered equivalent to another Profiles instance created via
Profiles.of() with the exact same expressions. This makes it difficult
to mock invocations of Environment#acceptsProfiles(Profiles) -- for
example, when using a mocking library such as Mockito.
This commit makes Profiles instances created via Profiles.of()
"comparable" by implementing equals() and hashCode() in ParsedProfiles.
Note, however, that equivalence is only guaranteed if the exact same
profile expression strings are supplied to Profiles.of(). In other
words, Profiles.of("A & B", "C | D") is equivalent to
Profiles.of("A & B", "C | D") and Profiles.of("C | D", "A & B"), but
Profiles.of("X & Y") is not equivalent to Profiles.of("X&Y") or
Profiles.of("Y & X").
Closes gh-25340
Prior to this commit, SocketUtils used System.currentTimeMillis() for
the seed for the java.util.Random instance used internally. The use of
the milliseconds value returned by currentTimeMillis() can lead to
collisions for randomly selected free ports for tests executing in
parallel on the same computer.
This commit therefore switches to System.nanoTime() for the Random seed
used in SocketUtils in an attempt to avoid such collisions for tests
executing in parallel in different JVMs on the same computer.

This commit removes load time weaving, CGLIB and Objenesis support
from native images.
GraalDetector has been removed for now because of
https://github.com/oracle/graal/issues/2594. It should be reintroduced
when this bug will be fixed with NativeImageDetector class name.
Closes gh-25179
This commit introduces a spring.xml.ignore system property
which when set to true avoid initializing XML infrastructure.
A typical use case is optimizing GraalVM native image footprint
for applications not using XML. In order to be effective, those
classes should be initialized at build time:
- org.springframework.util.DefaultPropertiesPersister
- org.springframework.core.io.support.PropertiesLoaderUtils
- org.springframework.web.servlet.function.support.RouterFunctionMapping
- org.springframework.web.client.RestTemplate
- org.springframework.web.servlet.mvc.method.annotation.ExceptionHandlerExceptionResolver
- org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport
- org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter
- org.springframework.http.converter.support.AllEncompassingFormHttpMessageConverter
- org.springframework.http.codec.support.BaseDefaultCodecs
- org.springframework.beans.PropertyEditorRegistrySupport

Gradle build.
Thanks to a tip from @melix, this commit aims to ensure that the
spring-core JAR is "reproducible".

This commit avoids duplicate addition of void.class to the temporary
primitiveTypes Set in the static initialization block in ClassUtils.

Prior to this commit (and the previous one), the `AntPathStringMatcher`
(inner class of `AntPathmatcher`) would compile `Pattern` instances and
use regex matching even for static patterns such as `"/home"`.
This change introduces a shortcut in the string matcher algorithm to
skip the `Pattern` creation and uses `String` equality instead.
Static patterns are quite common in applications and this change can
bring performance improvements, depending on the mix of patterns
configured in the web application.
In benchmarks (added with this commit), we're seeing +20% throughput
and -40% allocation. This of course can vary depending on the number of
static patterns configured in the application.
Closes gh-24887
Prior to this commit, `MediaType.parseMediaType` would already rely on
the internal LRU cache in `MimeTypeUtils` for better performance. With
that optimization, the parsing of raw media types is skipped for cached
elements.
But still, `MediaType.parseMediaType` would first get a cached
`MimeType` instance from that cache and then instantiate a
`new MediaType(type, subtype, parameters)`. This constructor not only
replays the `MimeType` checks on type/subtyme tokens and parameters, but
it also performs `MediaType`-specific checks on parameters.
Such checks are not required, as we're using an existing `MimeType`
instance in the first place.
This commit adds a new protected copy constructor (skipping checks) in
`MimeType` and uses it in `MediaType.parseMediaType` as a result.
This yields interesting performance improvements, with +400% throughput
and -40% allocation/call in benchmarks. This commit also introduces a
new JMH benchmark for future optimization work.
Closes gh-24769
Prior to this commit, the loadFactoryNames() and loadFactories() methods
in SpringFactoriesLoader effectively used a different default
ClassLoader.
This commit ensures that the ClassLoader for SpringFactoriesLoader.class
is now consistently used as the default ClassLoader.
Closes gh-24992
This commit ensures that the static cache in SpringFactoriesLoader
contains unmodifiable lists of unique names of factory implementations.
See gh-24985
Prior to this commit, SpringFactoriesLoader discovered all registered
factory implementations for a given factory type even if duplicates
were registered within a single META-INF/spring.factories file or in
multiple such files in the classpath.
This commit updates the internals of SpringFactoriesLoader so that
duplicate registrations are ignored, thereby aligning with the
well-known semantics for java.util.ServiceLoader in this regard.
Closes gh-24985
- Build Scan plugin is now Gradle Enterprise plugin applied in settings
- Compile task dependencies are now defined through classpath
- Test fixture publication can be disabled through public API

This commit moves the toString() implementation for synthesized
annotations from TypeMappedAnnotation to
SynthesizedMergedAnnotationInvocationHandler in order to take advantage
of the synthesized annotation attribute value cache introduced in
72b1abd226.
Closes gh-24970
Prior to the introduction of the MergedAnnotation API in Spring Framework
5.2, our SynthesizedAnnotationInvocationHandler utilized a cache for
annotation attribute values; whereas, the new
SynthesizedMergedAnnotationInvocationHandler has no such caching in
place.
Issues such as gh-24961 indicate a regression in performance caused by
the lack of such an attribute value cache. For example, the required
attribute in @RequestParam is looked up using the internal meta-model
in the MergedAnnotation API twice per request for each @RequestParam in
a given controller handler method.
This commit reintroduces the attribute value cache to avoid the
unnecessary performance overhead associated with multiple lookups of
the same attribute in a synthesized annotation. This applies not only
to direct attribute method invocations but also to invocations of
equals() and hashCode() on a synthesized annotation.
Note, however, that this commit does NOT address multiple lookups of
annotation attribute values for invocations of toString(). That behavior
currently remains unchanged in the implementation of
org.springframework.core.annotation.TypeMappedAnnotation.toString().
Closes gh-24970
Commit 31fa1569c5 introduced initial support for avoiding unnecessary
annotation synthesis in the MergedAnnotation API; however, it only
avoided synthesis for annotations that do not declare any attributes.
This commit reworks this support to avoid unnecessary annotation
synthesis for annotations that declare attributes.
Specifically, this commit introduces a new `isSynthesizable()` method
in AnnotationTypeMapping that allows the "synthesizable" flag to be
computed once and cached along with the other metadata already cached
in AnnotationTypeMapping instances. TypeMappedAnnotation now delegates
to this new method when determining whether it should synthesize an
annotation.
Closes gh-24861
Prior to Spring Framework 5.2, some of our annotation utilities would
not synthesize an annotation if it was already synthesized or not
synthesizable (i.e., did not declare local aliases via @AliasFor and
did not declare attributes that could override attributes in the
meta-annotation hierarchy above the given annotation); however, we lost
most of this functionality with the introduction of the new
MergedAnnotations API.
This commit revises the implementation of createSynthesized() in
TypeMappedAnnotation so that, for invocations of
MergedAnnotation.synthesize() and indirectly for invocations of
AnnotatedElementUtils.findMergedAnnotation(), etc.:
1. An annotation that was previously synthesized will not be
synthesized again.
2. An annotation that is not "synthesizable" will not be synthesized.
For both of the above use cases, the original annotation is now
returned from createSynthesized().
