Comment 2 Jaroslav Tulach 2012-01-24 10:16:12 UTC 
The method FileUtil.getMIMEType needs to open a stream from time to time (which can possibly be eliminated by specifying the extensions one is searching for). If the call has to be done outside of AWT, then it has to be rescheduled on the caller side: org.netbeans.modules.java.hints.infrastructure.HintAction.getCurrentFile(:167)
