[PR] Fix AccumuloVFSClassLoader race condition [accumulo]
BukrosSzabolcs opened a new pull request, #5835:
URL: https://github.com/apache/accumulo/pull/5835
Run into a race condition:
- ThreadA sets localLoader to null
- ThreadA waits for lock
- ThreadB has the lock
- ThreadB initializes loader and returns
- ThreadA gets the lock
- ThreadA finds that loader is not null, but localLoader is so turns into an infinite loop and prevents master/ts init
We should set localLoader if we find someone else already initialized loader to prevent this.

Merged this to main -sours because the class does not exist in main, it was moved to https://github.com/apache/accumulo-classloaders. I took a quick look there and did not see a similar problem, just looked the beginning of while loops looking for a similar pattern.
