Description

The attached test crashes with the following message on Linux SUSE9 ia32:

SIGSEGV in VM code.
Stack trace:
1: locktable_get_fat_monitor (/nfs/ins/proj/drl/coreapi/esemukhi/svn/drlvm/trunk/vm/thread/src/thread_native_thin_monitor.c:655)
2: hythread_thin_monitor_try_enter (/nfs/ins/proj/drl/coreapi/esemukhi/svn/drlvm/trunk/vm/thread/src/thread_native_thin_monitor.c:310)
3: IP is 0x416A05BD <native code>
4: ?? (??:-1)
<end of stack trace>
Segmentation fault

If to remove the "synchronized" modifier from the "test()" method declaration, the test passes.

On SUSE9 Linux em64t the crash does not depend on the "synchronized" modifier: it just crashes with the wording:
Segmentation fault
(see HARMONY-2972)

The attached test is the slightly modified smoke test stress.Stack.
