We run checkstyle in parallel in our ant build, and occasionally it deadlocks.

I took a thread dump (attached) and it looks like all the checkstyle threads
are runnable, but Parallel is stuck waiting, so I think this might be an Ant
problem.

Ant 1.8.2-3 and checkstyle-5.3.jar

Happens once or twice a week, so intermittently reproducible, but usually works
fine the next run so not major.
