Michael Dick updated OPENJPA-1119:
----------------------------------

    Remaining Estimate: 0h
     Original Estimate: 0h

Thanks Rick. I haven't found a value that works on my 64 bit config with Sun JDK6 (tried up
to 1024m which seems extreme). When I find a value that works I'll commit the patch.
