It would great if you can provide steps how to reproduce it. Thanks.
Comment 3 J Bachorik 2011-09-12 08:06:58 UTC 
IMHO, org.openide.text.EditorSupportLineSet$SupportLine.show() method should be the one making sure the subsequent calls of Window API are carried out on EDT.
Comment 4 javydreamercsw 2011-09-15 16:31:36 UTC 
I got the same issue but when running my application. The code was unchanged from yesterday and it worked on the previous daily build just fine. It points to the TopComponent's constructor code generated by the IDE:

setToolTipText(NbBundle.getMessage(UserListTopComponent.class, "HINT_UserListTopComponent"));

java.lang.IllegalStateException: Problem in some module which uses Window System: Window System API is required to be called from AWT thread only, see http://core.netbeans.org/proposals/threading/
	at org.netbeans.core.windows.WindowManagerImpl.warnIfNotInEDT(WindowManagerImpl.java:1531)
	at org.netbeans.core.windows.WindowManagerImpl.topComponentDisplayNameChanged(WindowManagerImpl.java:1176)
	at org.openide.windows.TopComponent.setName(TopComponent.java:954)

I was not sure if this should be a different bug, but from the stack trace it looks to be the same.
Comment 5 J Bachorik 2011-10-05 18:06:33 UTC 
@javydreamercsw: Well, it is not the same. The message is, but it is reached by completely different code paths.

@Petr Cyhelsky: How did you manage to get this exception? :) The code for opening a document at the given line is there but it is not effectively called as the only value the line arguments can have as of now is -1 and in that case the code causing this exception is not executed at all :)
