Prior to this commit, the `ConcurrentLruCache` implementation would use
arrays of `AtomicReference` as operation buffers, and the buffer count
would be calculated with the nearest power of two for the CPU count.
This can result in significant heap memory usage as each
`AtomicReference` buffer entry adds to the memory pressure. As seen in
FasterXML/jackson-databind#3665, this can add a significant overhead for
no real added benefit for the current use case.
This commit changes the current implementation to use
`AtomicReferenceArray` as buffers and reduce the number of buffers.
JMH benchmarks results are within the error margin so we can assume that
this does not change the performance characteristics for the typical use
case in Spring Framework.
Fixes gh-29520
For a transition period, LocalVariableTableParameterNameDiscoverer logs a warning for each successful resolution attempt now, suggesting that -parameters was missed.
See gh-29531
See gh-29559
LocalVariableTableParameterNameDiscoverer is not registered by default anymore now.
Java sources should be compiled with `-parameters` instead (available since Java 8).
Also retaining standard Java parameter names for all of Spring's Kotlin sources now.

As a follow up to 332b25b680, this commit consistently avoids the use of
reflection for annotation attribute method invocations.

Closes gh-29448
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.
