* @bug 8167108 8266130
* @summary converted from VM Testbase nsk/jvmti/SuspendThread/suspendthrd003.
* VM Testbase keywords: [jpda, jvmti, noras]
* VM Testbase readme:
* DESCRIPTION
* Same test as suspendthrd001 with additional calls to
* SuspendThread() and ResumeThread() while threads are exiting.
* Failing criteria for the test are:
* - failures of used JVMTI functions.
* COMMENTS
* Derived from nsk/jvmti/SuspendThread/suspendthrd001.
