IllegalMonitorStateException in URLClassLoader

[Juerg Lehni]

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.
