Not sure how much it helps, but Java has a built-in thread deadlock detector (which may or may not fire here, since it 
only detects deadlocks where the locks in question are all Java-level locks)

I have code that I can contribute that runs a watchdog thread that queries the Java deadlock detector every 2 seconds 
and kills the program when a deadlock is detected.

Of course, it may be simpler and safer to simply surround the relevant tests with a brute-force-5-min-timeout-and-kill.
