Mike Drob commented on SOLR-16127:
----------------------------------
cc: [~caomanhdat] what was the original intent of the design here? I have a PR
up to demonstrate the problem, I'm not sure if we can ever get into a situation
where a waiting thread is interrupted without the rest of the server going down
anyway, but I also don't like to hope that a situation is impossible to avoid
potential bugs.

> If a thread is interrupted while waiting to acquire a maxThreads semaphore
> permit, then it does not clean up the corresponding entry in striped lock,
> which may prevent future threads from executing even when enough semaphore
> permits become available.
