Description Denis Anisimov 2008-03-20 15:29:52 UTC 
Current version of IDE freezes on file open.

Steps to reproduce :
1) Open Java project.
2) Choose some Java file in project explorer.
As result the IDE is in deadlock.

I believe this the reason of this deadlock is last changes in CloneableEditor.
Please see history of changes:
http://hg.netbeans.org/main/log/f26672d69b54/openide.text/src/org/openide/text/CloneableEditor.java

With this version of CloneableEditor  :
http://hg.netbeans.org/main/file/41c254473c98/openide.text/src/org/openide/text/CloneableEditor.java
I'm able to avoid deadlock and all works fine.
This changes was done 2 days ago.

But with changes after this
Comment 1 Denis Anisimov 2008-03-20 15:33:20 UTC 
Sorry , accidentally submit issue without full description.

So, this deadlock appears with some changes after fix for #130272.
It seems these all changes are done by Jaroslav Tulach.
Could you please fix this.
Thanks.

For the record: please see issue #130701 for the thread dump and stack trace.
Comment 6 Jesse Glick 2008-03-20 20:32:05 UTC 
I think fixed by backing out #0c3e24bd6df8, but Yarda will need to confirm what is going on.
Comment 7 Jesse Glick 2008-03-20 20:43:52 UTC 
In case it was not clear: I did back it out, as #39dd35de782d (merged as #41a554bdbc18) in main which seems to fix
things for me at least.
