Headless Testcases crashes after completion of the Testing in Win32

This Testcase use two threads. In one thread, Tests are executed. The other Thread monitors the first thread. The second thread waits till the testing thread to die, using join().

Once the Testing thread is completed (testing is over), the second thread calls System.exit(0) to stop the testing.

When System.exit(0) is called the Testcase crashes giving "EXCEPTION_ACCESS_VIOLATION"

Attached here with is the log files, report, sample code (testcase for one scenario)
