Comment 1 Martin Entlicher 2015-04-03 08:44:23 UTC 
Wasn't some exception thrown prior to the deadlock?
Comment 2 everflux 2015-04-03 08:45:52 UTC 
Yes a NPE that was reported by the regular exception reporter imho. But that was a couple of minutes before, so I thought it was unrelated.
Comment 3 Martin Entlicher 2015-04-03 09:20:31 UTC 
Thanks for mentioning that. There were several NPEs thrown (issue #251557) and one was:
java.lang.NullPointerException
	at org.netbeans.spi.debugger.ActionsProvider$ContextAware.isCurrentMIMETypeIn(ActionsProvider.java:408)
	at org.netbeans.spi.debugger.ActionsProvider$ContextAware.isEnabled(ActionsProvider.java:278)

...
which broke the registration of action providers. The threads are waiting to finish the registration, which never happened.
Comment 4 Martin Entlicher 2015-04-03 09:25:24 UTC 
This deadlock should not occur after the fix of issue #251557, to prevent from such future possible deadlocks, the notification is done in a finally block:
