Test : nsk/jvmpi/GetThreadStatus/thrstat003
TestBase : testbase_nsk
VM : server
Mode : mixed
Platform : x86
OS : 5.8, Redhat Linux 7.2, Windows XP

----------------------------------------
Steps to reproduce
================
1. cd /net/sqesvr.eng/export/vsn/GammaBase/Bugs/{BugID}
2. sh doit.sh $JAVA_HOME -server -Xmixed

This test exercises JVMPI function GetThreadStatus() for
three threads with different status.

While executing test on an Intel x86 platform with ServerVM in -Xmixed
mode an NullPoinerException occured in the third thread's Java code:

class thrstat003c implements Runnable {
    public void run() {
        thrstat003.contendCount3++;
        while (thrstat003.contendCount3 != 2) {
            Thread.yield(); <--------------------- NullPointerException
        }
        Thread.yield(); // to have guaranteed Thread.yield();
        thrstat003.contendCount3++;
    }
}

and the test failed with error message:

  Thread thr3 (0x8190318) status expected: 0x4001, got: 0x1

Or sometimes VM crashes with the diagnostics:

#
# HotSpot Virtual Machine Error : 4
# Error ID : 4F530E43505002E6
# Please report this error at
# http://java.sun.com/cgi-bin/bugreport.cgi
#
# Java VM: Java HotSpot(TM) Server VM (1.4.1-beta-b14 mixed mode)
#
# An error report file has been saved as hs_err_pid6060.log.
# Please refer to the file for further information.
#

On ClientVM and in other VM modes the test passes successfully.

Here is test output with NullPointerException:
