This commit introduces DataBuffer::readableByteBuffers and
DataBuffer::writableByteBuffers, allowing restricted access to the
ByteBuffer used internally by DataBuffer implementations.

Originally, `Base64Utils` was providing base64 encoding and decoding
utilities, bridging to commons-codecs or Java 8, if available. Since
then, only the Java 8 variant remains and Spring Framework 6 requires
now Java 17. This utility class doesn't provide additional checks or
syntactic sugar over what's in Java already.
As a result, this commit deprecates this class in favor of `Base64` and
schedules the removal of this class completely.
Closes gh-28434
Prior to this commit, there was a bug in the implementation of
StandardRepeatableContainers.computeRepeatedAnnotationsMethod() which
has existed since Spring Framework 5.2 (when
StandardRepeatableContainers was introduced). Specifically,
StandardRepeatableContainers ignored any repeatable container
annotation if it declared attributes other than `value()`. However,
Java permits any number of attributes in a repeatable container
annotation.
In addition, the changes made in conjunction with gh-20279 made the bug
in StandardRepeatableContainers apparent when using the
getMergedRepeatableAnnotations() or findMergedRepeatableAnnotations()
method in AnnotatedElementUtils, resulting in regressions for the
behavior of those two methods.
This commit fixes the regressions and bug by altering the logic in
StandardRepeatableContainers.computeRepeatedAnnotationsMethod() so that
it explicitly looks for the `value()` method and ignores any other
methods declared in a repeatable container annotation candidate.
Closes gh-29685
This commit ensures that giving an anonymous class for reflection hints
registration does not result in a NullPointerException, since the
canonical name of anonymous classes is null.

For a transition period, LocalVariableTableParameterNameDiscoverer logs a warning for each successful resolution attempt now, suggesting that -parameters was missed.

When a hint such as `graphql/*.*` is registered for resources that are
looked up via classpath scanning using a pattern such as
`classpath*:graphql/**/*.graphqls`, an appropriate pattern is in fact
registered in the generated `resource-config.json` file for GraalVM
native images; however, classpath scanning fails since GraalVM
currently does not make the `graphql` directory automatically available
as a classpath resource.
This can be very confusing and cumbersome for users since a file such
as `graphql/schema.graphqls` will not be discovered via classpath
scanning even though the file is present in the native image filesystem.
To address this, this commit automatically registers resource hints for
enclosing directories for a registered pattern.
If the GraalVM team later decides to perform automatic directory
registration, we can then remove the code introduced in conjunction
with this issue.
Closes gh-29403
Prior to this commit, it was not possible to register the root
directory as a native image resource; however, it is necessary to be
able to register the root directory to enable classpath scanning of the
root directory within a native image -- for example, to support
resource patterns such as `classpath*:/*.properties`.
This commit therefore relaxes the precondition check in the
ResourcePatternHint constructor to allow explicit registration of the
root directory.
Closes gh-29402
As can be seen in a modified version of the following example project,
attempting to access a resource discovered via classpath scanning
within a GraalVM native image -- for example via the Files.exists(...)
invocation in FileSystemResource -- currently results in a
ClosedFileSystemException since PathMatchingResourcePatternResolver
explicitly closes the native image FileSystem that backs `resource:`
resources.
Sample project: https://github.com/joshlong/spring-boot-3-aot-graphql
To address this issue, this commit removes the explicit close()
invocation for custom FileSystems after classpath scanning in
PathMatchingResourcePatternResolver.

DefaultValueStyler hard codes conventions for styling that are verbose
and do not align well with standard toString() implementations in the
JDK for arrays, collections, and maps. Furthermore, the default styling
for classes and methods may not be suitable or desirable for certain
use cases.
To address these shortcomings, this commit introduces a
SimpleValueStyler for use with ToStringCreator. The default behavior of
SimpleValueStyler aligns with toString() implementations for arrays,
collections, and maps in the JDK, and styling for classes and methods
is configurable via a dedicated constructor.
Closes gh-29381
LeakAwareDataBufferFactory#checkForLeaks automatically waits up to 5
sec for buffers to be released, which could be used as a way of
awaiting on some async logic to complete, and as long as buffers are
released, it shouldn't be long. However, the leak test in
LeakAwareDataBufferFactoryTests actually expects to find a leak, and
always ends up waiting the full 5 seconds.
This change, makes the wait configurable, with the no-arg method
using 0 (no waiting). AbstractLeakCheckingTests uses 1 second by
default since ResourceRegionEncoderTests did fail locally. If more
tests need this, we can adjust the settings.
Prior to this commit, searches for non-public repeatable annotations
failed with error messages similar to the following, since the
repeatable annotation's container's `value()` method could not be
invoked via reflection.
JDK 8:
java.lang.IllegalAccessError: tried to access class
org.springframework.core.annotation.NestedRepeatableAnnotationsTests$A
from class com.sun.proxy.$Proxy12
JDK 17:
java.lang.IllegalAccessError: failed to access class
org.springframework.core.annotation.NestedRepeatableAnnotationsTests$A
from class jdk.proxy2.$Proxy12
(org.springframework.core.annotation.NestedRepeatableAnnotationsTests$A
is in unnamed module of loader 'app'; jdk.proxy2.$Proxy12 is in module
jdk.proxy2 of loader 'app')
This commit makes it possible to search for non-public repeatable
annotations by first attempting to invoke the repeatable annotation's
container's `value()` method via the container's InvocationHandler (if
the container is a JDK dynamic proxy) and then falling back to
reflection for the method invocation if an error occurs (such as a
SecurityException).
Closes gh-29301
