Maybe try just `--stacktrace` without `--debug`, since I guess `--debug` may interfere concurrency somehow. Anyways, I appreciate your effort to share a sample project.

Thank you all for the reports. This is very helpful.

The `OverlappingFileLockException` indicates that multiple threads on the same JVM machine were able to enter into the same section of the code at the same time that is guarded by...

@robert-elles @pschichtel if possible, please share a full thread dump on a deadlock, as it tells which thread is blocked on which thread doing what.
