Commit 1f0cf759092beb031ccc2e5a6950f239f15b5b55 by GitHub
Performance improvement: synchronize to java.util.concurrent.locks switch to improve performance with VirtualThreads (#2116)

This change improves EclipseLink performance with higher versions of the JDK (21 and above).
It's about replacement of synchronized keyword and wait(), notify() methods by objects from java.util.concurrent.locks.* package.
Additionally there are some new performance tests to verify it.
