| * |
| * @summary converted from VM Testbase nsk/monitoring/ThreadInfo/getLockName/getlockname001. |
| * VM Testbase keywords: [quick, monitoring] |
| * VM Testbase readme: |
| * DESCRIPTION |
| * The test checks that |
| * ThreadInfo.getLockName() |
| * returns correct string for a blocked thread and for a running thread. |
| * The test starts an instance of MyThread, waits to be sure that it is blocked |
| * on "backDoor" object and then calls getLockName() for it. Since the thread |
| * is blocked, the expected string is: |
| * backDoor.getClass().getName() + "<at>" |
| * + Integer.toHexString(System.identityHashCode(backDoor)) |
| * After that current thread is checked. Since it is not blocked on any object, |
| * getLockName() must return null. |
| * Testing of the method does not depend on the way to access metrics, so |
| * only one (direct access) is implemented in the test. |
| * COMMENT |
| * Fixed the bug |
| * 4989235 TEST: The spec is updated accoring to 4982289, 4985742 |
| * Updated according to: |
| * 5024531 Fix MBeans design flaw that restricts to use JMX CompositeData |
