(cherry picked from commit 3b6be3d4d3)
The Spliterators returned by values, entrySet, and keySet incorrectly
reported the SIZED characteristic, instead of CONCURRENT. This could
lead to bugs when the map is concurrently modified during a stream
operation.
For keySet and values, the incorrect characteristics are inherited from
AbstractMap, so to rectify that the respective methods are overridden,
and custom collections are provided that report the correct Spliterator
characteristics.

This commit ensures that both `VirtualThreadDelegate` implementations
expose the same public API. If not, JAR verification fails with the
following message:
```
jar --validate --file spring-core-6.2.13-SNAPSHOT.jar
entry: META-INF/versions/21/org/springframework/core/task/VirtualThreadDelegate.class, contains a class with different api from earlier version
```
Fixes gh-35773
When JAR manifest Class-Path entries contain absolute paths (as Gradle
creates on Windows for long classpaths), PathMatchingResourcePatternResolver
incorrectly rejected them.

When concurrency limiting is enabled via setConcurrencyLimit() and
thread creation fails in doExecute() (e.g., OutOfMemoryError from
Thread.start()), the concurrency permit acquired by beforeAccess()
is never released because TaskTrackingRunnable.run() never executes.
This causes the concurrency count to permanently remain at the limit,
causing all subsequent task submissions to block forever in
ConcurrencyThrottleSupport.onLimitReached().
Root cause:
- beforeAccess() increments concurrencyCount
- doExecute() throws Error before thread starts
- TaskTrackingRunnable.run() never executes
- afterAccess() in finally block never called
- Concurrency permit permanently leaked
Solution:
Wrap doExecute() in try-catch block in the concurrency throttle path
and call afterAccess() in catch block to ensure permit is always
released, even when thread creation fails.
The fix only applies to the concurrency throttle path. The
activeThreads-only path does not need fixing because it never calls
beforeAccess(), so there is no permit to leak.
Test approach:
The test simulates thread creation failure and verifies that a
subsequent execution does not deadlock. The first execution should
fail with some exception (type doesn't matter), and the second
execution should complete within timeout if the permit was properly
released.

Prior to this commit, getPubliclyAccessibleMethodIfPossible() in
ClassUtils incorrectly returned a hidden static method as an
"equivalent" method for a static method with the same signature;
however, a static method cannot be overridden and therefore has no
"equivalent" method in a super type.
To fix that bug, this commit immediately aborts the search for an
"equivalent" publicly accessible method when the original method is a
static method.

As reported in gh-34651, `DataBuffer#getByte` can be inefficient for
some implementations, as bound checks are performed for each call.
This commit introduces a new `forEachByte` method that helps with
traversing operations without paying the bound check cost for each byte.
Closes gh-35623
Prior to this commit, annotations were not found on parameters in an
overridden method unless the method was public. Specifically, the
search algorithm in AnnotatedMethod did not consider a protected or
package-private method in a superclass to be a potential override
candidate. This affects parameter annotation searches in
spring-messaging, spring-webmvc, spring-webflux, and any other
components that use or extend AnnotatedMethod.
To address that, this commit revises the search algorithm in
AnnotatedMethod to consider all non-final declared methods as potential
override candidates, thereby aligning with the search logic in
AnnotationsScanner for the MergedAnnotations API.
Closes gh-35349
Prior to this commit, gh-32097 added native support for Jetty for both
client and server integrations. The `JettyDataBufferFactory` was
promoted as a first class citizen, extracted from a private class in the
client support. To accomodate with server-side requirements, an extra
`buffer.retain()` call was performed.
While this is useful for server-side support, this introduced a bug in
the data buffer factory, as wrapping an existing chunk means that this
chunk is already retained.
This commit fixes the buffer factory implementation and moved existing
tests from mocks to actual pooled buffer implementations from Jetty.
The extra `buffer.retain()` is now done from the server support, right
before wrapping the buffer.
Fixes gh-35319
Prior to this commit, the MergedAnnotations support (specifically
AnnotationsScanner) and AnnotatedMethod did not find annotations on
overridden methods in type hierarchies with unresolved generics.
The reason for this is that ResolvableType.resolve() returns null for
such an unresolved type, which prevents the search algorithms from
considering such methods as override candidates.
For example, given the following type hierarchy, the compiler does not
generate a method corresponding to processOneAndTwo(Long, String) for
GenericInterfaceImpl. Nonetheless, one would expect an invocation of
processOneAndTwo(Long, String) to be @Transactional since it is
effectively an invocation of processOneAndTwo(Long, C) in
GenericAbstractSuperclass, which overrides/implements
processOneAndTwo(A, B) in GenericInterface, which is annotated with
@Transactional.
However, the MergedAnnotations infrastructure currently does not
determine that processOneAndTwo(Long, C) is @Transactional since it is
not able to determine that processOneAndTwo(Long, C) overrides
processOneAndTwo(A, B) because of the unresolved generic C.
interface GenericInterface<A, B> {
@Transactional
void processOneAndTwo(A value1, B value2);
}
abstract class GenericAbstractSuperclass<C> implements GenericInterface<Long, C> {
@Override
public void processOneAndTwo(Long value1, C value2) {
}
}
static GenericInterfaceImpl extends GenericAbstractSuperclass<String> {
}
To address such issues, this commit changes the logic in
AnnotationsScanner.hasSameGenericTypeParameters() and
AnnotatedMethod.isOverrideFor() so that they use
ResolvableType.toClass() instead of ResolvableType.resolve(). The
former returns Object.class for an unresolved generic which in turn
allows the search algorithms to properly detect method overrides in
such type hierarchies.

Refine the StringUtils#uriDecode method in the following ways:
- Use a StringBuilder instead of ByteArrayOutputStream, and only decode
%-encoded sequences.
- Use HexFormat.fromHexDigits to decode hex sequences.
- Decode to a byte array that is only allocated if encoded sequences are
encountered.
This commit adds another optimization mainly for the use case where
there is no encoded sequence, and updates the Javadoc of both
StringUtils#uriDecode and UriUtils#decode to match the implementation.

If an application depends on automatic type conversion from
java.time.Instant to java.sql.Timestamp, the ObjectToObjectConverter
performs the conversion based on convention, by using reflection to
invoke Timestamp.from(Instant).
However, when running in a native image a user needs to explicitly
register runtime hints for that particular use of reflection.
To assist users who are running their applications in a native image,
this commit automatically registers the necessary runtime hints for
Timestamp.from(Instant) so that users do not have to.

In order to avoid unnecessary use of reflection and to simplify native
image deployments, this commit introduces explicit support for
automatic conversions from java.util.Date to java.time.Instant and vice
versa.
To achieve that, this commit introduces an InstantToDateConverter and a
DateToInstantConverter and registers them automatically in
DefaultConversionService.

Update `SpringFactoriesLoader` so that the cache stores only the
factories and not the complete loader.
Prior to this commit, if a cache entry was added with the thread
context classloader, the loader instance would be added and the
classloader stored. If the thread context classloader subsequently
changes, and a call is made to `forDefaultResourceLocation` with
`null` for the classloader, the cached entry would be used which
contains the older classloader.
