Description

It might be related to NETBEANS-373. It appears that the system deadlocks when creating the UI. The FX thread is the Native Ui thread on a mac. It appears that FX is waiting for Swing, which is waiting for the native thread to do something. Not very sure about it. Here are the stack traces I got (might be different each time):
