I've had similar problems quite a while ago when Jython was called 
JPython and had version numbers less than two. Increasing the heap size 
helped, but you may want to try something more substantial than 50 MB. 
Give it everything your machine has. I managed to compile everything 
when the heapsize was at least 256 MB. A fast machine comes handy, too :-)
