This commit introduces a `@CheckReturnValue` annotation,
inspired from org.jetbrains.annotations.CheckReturnValue,
that specifies that the method return value must be used.

Update `PathMatchingResourcePatternResolver` so that in addition to
searching the `java.class.path` system property for classpath enties,
it also searches the `MANIFEST.MF` files from within those jars.
Prior to this commit, the `addClassPathManifestEntries()` method
expected that the JVM had added `Class-Path` manifest entries to the
`java.class.path` system property, however, this did not always happen.
The updated code now performs a deep search by loading `MANIFEST.MF`
files from jars discovered from the system property. To deal with
potential performance issue, loaded results are also now cached.
The updated code has been tested with Spring Boot 3.3 jars extracted
using `java -Djarmode=tools`.
See gh-33705
Replaced the hardcoded '/' path separator with the `PATH_SEPARATOR` constant
to improve code readability and maintainability. This change ensures
consistency across the codebase when handling path separators.
Closes gh-33646
Align internal handling and contracts. The core copy could do without
those contracts, but it helps with alignment, and it's internal to
the implementation.

Commit 47f88e123f introduced support for invoking init/destroy/SpEL
methods via public types whenever possible. To achieve that,
getInterfaceMethodIfPossible() was modified so that it only returned
interface methods from public interfaces; however, we have learned that
third parties relied on the previous behavior which found any interface
method (even in non-public interfaces).
In light of the above, this commit partially reverts commit 47f88e123f
in order to reinstate getInterfaceMethodIfPossible() in non-deprecated
form with its previous behavior.
See gh-33216
Prior to this commit, when invoking init methods and destroy methods
for beans as well as methods within Spring Expression Language (SpEL)
expressions via reflection, we invoked them based on the "interface
method" returned from ClassUtils.getInterfaceMethodIfPossible(). That
works well for finding methods defined in an interface, but it does not
find public methods defined in a public superclass.
For example, in a SpEL expression it was previously impossible to
invoke toString() on a non-public type from a different module. This
could be seen when attempting to invoke toString() on an unmodifiable
list created by Collections.unmodifiableList(...). Doing so resulted in
an InaccessibleObjectException.
Although users can address that by adding an appropriate --add-opens
declaration, such as --add-opens java.base/java.util=ALL-UNNAMED, it is
better if applications do not have to add an --add-opens declaration
for such use cases in SpEL. The same applies to init methods and
destroy methods for beans.
This commit therefore introduces a new
getPubliclyAccessibleMethodIfPossible() method in ClassUtils which
serves as a replacement for getInterfaceMethodIfPossible().
This new method finds the first publicly accessible method in the
supplied method's type hierarchy that has a method signature equivalent
to the supplied method. If the supplied method is public and declared
in a public type, the supplied method will be returned. Otherwise, this
method recursively searches the class hierarchy and implemented
interfaces for an equivalent method that is public and declared in a
public type. If a publicly accessible equivalent method cannot be
found, the supplied method will be returned, indicating that no such
equivalent method exists.
All usage of getInterfaceMethodIfPossible() has been replaced with
getPubliclyAccessibleMethodIfPossible() in spring-beans and
spring-expression. In addition, getInterfaceMethodIfPossible() has been
marked as deprecated in favor of the new method.
As a bonus, the introduction of getPubliclyAccessibleMethodIfPossible()
allows us to delete a fair amount of obsolete code within the SpEL
infrastructure.

Prior to this commit, the ConversionService failed to convert a primitive
array (such as int[]) to an Object[] due to an error in the logic in
ArrayToArrayConverter.
This commit addresses this by augmenting the "can bypass conversion"
check in ArrayToArrayConverter to ensure that the supplied source object
is an instance of the target type (i.e., that the source array can be
cast to the target type array without conversion).
