Reassigning to "java".
Comment 6 Max Sauer 2008-07-30 08:54:14 UTC
Seems more like debugger issue to me. Please reassign back in case I'm mistaken, thanks.
Comment 7 Daniel Prusa 2008-07-30 22:43:13 UTC
I have made a fix preventing Finish Debugger action to be still enabled and non-functional:
changeset d9e81876bce9 in main

The second thread dump does not seem to be related to the debugger. AWT thread is blocked at


which is called by

Reassigning back for further evaluation.

Comment 10 Jan Becicka 2008-10-01 08:57:29 UTC
Last dump is from gsf, isn't it?
Comment 11 David Strupl 2009-01-14 14:35:30 UTC
Moving from ruby/GSF to editor/CSL. Step one: assign to myself ;-)
Comment 12 David Strupl 2009-01-14 14:42:59 UTC
Step 2: trying to make the owner not myself but the owner of the subcomponent.
Comment 13 Miloslav Metelka 2009-03-23 16:11:10 UTC
Is this still relevant?
Comment 14 Vitezslav Stejskal 2009-03-24 14:43:30 UTC
Not sure. From the threaddump it looks like a clash between AWT and "GSF Source Worker Thread".

AWT: BaseKit.DefaultKeyTypedAction calls insertString under a document writelock;
JSPKit$JspDefaultKeyTypedAction.insertString calls reformat which tries to acquire the GSF parsing infrastructure's lock.

GSF: A task is running which tries to readlock a document.
Comment 15 pribyl 2009-04-17 13:48:25 UTC
Any chance this has been resolved? I am little confused from the latest comments.
Issue has INCOMPLETE status - are we really waiting for additional info from the reporter?

Thanks for any update
Comment 16 Max Sauer 2009-04-17 16:22:16 UTC
It would be nice if the reporter will tell us if it still happen for him in latest trunk builds... Thanks.
Comment 17 David Strupl 2009-06-08 13:59:43 UTC
Marek, these are yours now ...
Comment 18 mslama 2009-07-09 14:55:24 UTC
Last deadlock is probably due to incorrect order of locking of document and internal old gsf parser lock. mfukala do you
remember if you already fixed this in past or not?
Comment 19 mslama 2009-07-09 15:02:02 UTC
Document locking in AWT thread is done at org.netbeans.editor.BaseKit$DefaultKeyTypedAction.actionPerformed.
Comment 20 Marek Fukala 2009-07-09 16:55:45 UTC
This is IMHO already fixed by my changes in JspKit$JspDefaultKeyTypedAction - the indent lock is acquired before locking
the document.
Comment 21 Marek Fukala 2009-07-09 16:56:54 UTC
closing as fixed
