Please, review the following test change. Issue : https://bugs.openjdk.java.net/browse/JDK-8071641 Webrev: http://cr.openjdk.java.net/~jbachorik/8071641/webrev.00/
The test fails very intermittently with NPE. This seems to be caused by a data race between Thread.getStatus() and ThreadMXBean.getThreadInfo() - thread state is reported as BLOCKED but the ThreadInfo still contains a stale information (lockname == null).
The solution would be re-retrieving the ThreadInfo until it reflects the actual thread state.
