| * @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. |
