While working on the following bug:

4434422 2/5 HS1.4 crashes with assertion at resourceArea.hpp, 48

I tried tweaking the test case a bit to fix a timing bug. I replaced
the existing thread synchronization mechanism with a barrier lock.

When FramePop() was called on the thread blocked on barrier, the
VM crashed with the java command:

#
# HotSpot Virtual Machine Error : 11
# Error ID : 4F530E43505002D9 01
# Please report this error at
# http://java.sun.com/cgi-bin/bugreport.cgi
#
# Java VM: Java HotSpot(TM) Client VM (1.4-internal interpreted mode)
#
# An error report file has been saved as hs_err_pid8517.log.
# Please refer to the file for further information.
#

% java -cp ~ ErrorID 4F530E43505002D9
os.cpp, 729

However, the java_g command output is more useful (requires the fix
for 4434422):
