Determine which thread owns a monitor

Question

Is there a way to tell, for a Java object, which Thread (or null) currently owns its monitor? Or at least a way to tell if the current thread owns it?

Answer 1

In Java 1.6 you can use Reflection to get this information.

ThreadMXBean tBean = ManagementFactory.getThreadMXBean();
ThreadInfo[] threadInfo = tBean .getThreadInfo(bean.getAllThreadIds(), true, true);
