If you close the DS editor with cmd-w immediately after a save, Eclipse will deadlock and you have to kill it.
I captured some additional info during this hang condition - I've deleted the stacks that did not appear relevant ...

CC'ing Dani as this looks like a JFace Text issue. Note, you are using e4. I also get the deadlock on 3.7M6.
I'll take a look
*** Bug 341606 has been marked as a duplicate of this bug. ***
Which version (build id) do you use?
The stack traces are from 4.1M6
Ugly! The DSComponentSection which should update the model (not UI) posts events synchronously into the UI thread. This is not allowed from within the reconciler thread as this can easily cause deadlocks like we see here. The DSOptionsSection has the same bug. Moving back to PDE UI inbox to see how they can get rid of this. I'll attach a dirty hack that will prevent the deadlock. However, it will cause widget disposed errors being written to .log.

Created attachment 192413 [details] Possible fix Ankur or Curtis: I've attached a possible fix but it needs some testing and a review. Also, a second check whether other places are also calling syncExec from the reconciler needs to be performed. BTW: Display.getDisplay() should never be used.
Moving to RC1
+1 for RC1.
+1, patch applied to HEAD. I don't see anywhere else in PDE where we are using syncExec when updating models. We are however using Display.getDefault() in the product editor and elsewhere, I filed bug 344759.
(In reply to comment #13) > +1, patch applied to HEAD. Curtis, it would be nice to mention the patch creator/author in the comment ;-).
(In reply to comment #14) > Curtis, it would be nice to mention the patch creator/author in the comment > ;-). Thanks for the patch Dani :) I did reassign the bug to you. I didn't mark this as contributed because you are a committer.

Verified in I20110512-2000 that the deadlock is gone. Filed bug 345987 for the remaining widget disposed exceptions.
