It is creating a core dump when -Xshare:on is used.

JDK : 1.5.0-b49 or 50 (no core on b48)
VM : client
switch/Mode : -Xshare:on
Platform[s] : Sol 10 sparc was tested. Will check other platforms later.

How to reproduce:
====================

1) cp /net/cady.sfbay/export/dtf/unified/knight-ws/suites/rmi_reliability/tiger/rmi_reliability.tar to your local dir

2) install local copy of jdk
2) cd rmi
3) launch_reliability.ksh jdk wordir_dir result_dir shell_location ./src 1 -showversion &

   (ex. launch_reliability.ksh `pwd`/j2sdk1.5 `pwd`/workdir `pwd`/result /usr/bin/ksh `pwd`/.src 1 -showversion)
   Note: This script can only take one VM flags

   There is more detail on README.

4) It is set to be complete in 1 hour, but about 15 to 30 min core dump created.
