You were right, Tom.

Both this problem and the mentioned deadlock were due to a half broken GCJ library. I used the installer from http:// hpc.sourceforge.net/ and was expecting it to work. Now after compiling gcc41 from DarwinPorts, both problems disappeared, and my app runs without such problems.

Offhand, no.  To me this says that something fairly fundamental has
gone wrong.  It shouldn't really be possible to get an
IllegalMonitorStateException from this code.
