[drlvm][thread manager] VM crashes with seg fault on the recursive call of a synchronized method
------------------------------------------------------------------------------------------------

                 Key: HARMONY-3010
                 URL: https://issues.apache.org/jira/browse/HARMONY-3010
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
            Reporter: Elena Semukhina
         Attachments: MyStack.java

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.
