 It works fine if -Xshare:off is supplied with the VM startup options.

Steps to Reproduce (be specific):
  1) Download the latest CodeGuide package from
     http://www.omnicore.com/download/codeguide-6.1-unix.tar.gz
  2) Extract it
  3) Modify the CodeGuide startup script to start the 1.5 VM
  4) Run the CodeGuide script
 
check attached errlog files for Redhat 7.1(err_rh71_log)
and Redhat 9(err_rh9_log).

Further information: It works fine if reduce the maximum heap size
parameter (-Xmx) to 256m while even 384m maximum heap size causes a
failure. At least an error message would be helpful. it can be reproduced
on different hardware with Debian GNU/Linux unstable as well,
log file attached:
