This application runs beautifully under Core 3 and 4, so something has changed under the Core 5 GCJ stuff  that I can't pinpoint.  I was unable to make my application run under core 5 without killing the GC and eventually went back to core 4.

Please try gcc41-java-gc-thread-attach-2.patch

gcc.gnu.org/PR13212

This patch will be in the next FC5 libgcj rpm update. It's already in 
Rawhide. I think it should solve your problem.
