* @test
*
* @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
*
* @library /vmTestbase
* /test/lib
* @run main/othervm nsk.monitoring.ThreadInfo.getLockName.getlockname001
