A DESCRIPTION OF THE PROBLEM :
Object.wait() with timeout set (30 seconds in my case) often (at least every couple of hours) hangs forever. While debugging the issue, I discovered that it suddenly unlocks after I run `jhsdb jstack --pid <pid>` and the application then continues operation.

Example stack trace (see thread `pool-2-thread-3`):
