We need to do something with this reports Davide. Definitely fix Deadlock Detector to provide more info automatically. For now closing as WONTFIX.
Deadlock detector is not part of the NB build any more due to the problem on JDK 8. Details here: http://bugs.sun.com/view_bug.do?bug_id=8016304 After the bug is fixed in JDK we can consider returning the deadlock detector back.
