 * DESCRIPTION
 *     The test exercises JVMDI function GetThreadState.  Java program launches
 *     a thread and for various thread states calls Thread.suspend()/resume()
 *     methods or JVMDI functions SuspendThread/ResumeThread. Then native method
 *     checkStatus is invoked. This method calls GetThreadState and checks if
 *     the returned values are correct and JVMTI_THREAD_STATE_SUSPENDED bit
 *     is set (or clear after resume).
 *     The thread statuses are:
 *       - JVMTI_THREAD_STATE_RUNNABLE
 *               if thread is runnable
 *       - JVMTI_THREAD_STATE_BLOCKED_ON_MONITOR_ENTER
 *               if thread is waiting to enter sync. block
 *       - JVMTI_THREAD_STATE_IN_OBJECT_WAIT
 *               if thread is waiting by object.wait()
 *     Failing criteria for the test are:
 *       - values returned by GetThreadState are not the same as expected;
 *       - failure of used JVMTI functions.
 * COMMENTS
 *     Converted the test to use GetThreadState instead of GetThreadStatus.
 *     Fixed according to 4387521 and 4427103 bugs.
 *     Fixed according to 4463667 bug.
 *     Fixed according to 4669812 bug.
 *     Ported from JVMDI.
 *     Fixed according to 4925857 bug:
 *       - rearranged synchronization of tested thread
 *       - enhanced descripton
