FC4 (x)maple 9.5.2 "connection to kernel lost", java problem?

[Des Johnston]

The java frontend to maple (9.5.2) that fires up with xmaple returns a
"connection to kernel lost" and opens up a window which doesn't accept 
input in FC4. Command line maple and the old-fashioned maple -cw 
interfaces are still working fine in FC4. There are no problems in FC3.

Has anyone found an FC4 workaround? Fiddling around with the built in java 
vm in maple didn't offer any improvement for me.
