Description _ ttran 2001-03-26 15:24:34 UTC 
in openide/core there are many places when Swing components are manipulated in
non-AWT thread.  This is a problem in general and a huge problem for the form
editor (deadlock).  A quick glance in the code found that at least   
CloneableOpenSupport.open() and EditorSupport.createCloneableTopComponent() are
the culprits.
Comment 1 Jan Zajicek 2001-03-27 07:56:24 UTC 
Yarda, do you have any hint how to find these places (simply and fast)?
Comment 2 Jaroslav Tulach 2001-03-28 11:18:22 UTC 
Marek, please fix the problem in CloneableOpenSupport.open () and also in
CloneableOpenSupport.close ()

The best way is to encapsulate the content of open () and close methods by 
Mutex.EVENT.writeAccess (Runnable) in the first case and Mutex.EVENT.writeAccess
(Mutex.Action) in the later.

I will modify the OpenAction to be always invoked in AWT thread meanwhile.

Marek, when you finish, set this bug to RESOLVED, REMIND so Trung can provide us
more places where we should continue with bug fixes.

Comment 4 Jiri Skrivanek 2001-03-28 11:51:51 UTC 
Deadlock (see attached thread dump) occured during gui testing of JDBC Form
wizard while opening generated Form (build 010327_2_IE). It may help.
Comment 5 mslama 2001-03-28 13:17:36 UTC 
Changes done in CloneableOpenSupport methods open() and close() as Yarda suggested.
Comment 6 Lukas Hasik 2002-01-10 15:22:06 UTC 
Trung, 

could you provide more places where to continue with bug fixes ?
Otherwise close this bug as fixed.
Comment 7 mslama 2002-02-18 13:39:42 UTC 
Closing this bug. If anybody finds suspicious code please reopen or
file new issue.
Comment 8 mslama 2002-02-18 13:41:08 UTC 
Mark as fixed.
Comment 9 Marian Mirilovic 2003-07-14 17:11:19 UTC 
Resolved for 3.4 or earlier, no new info since then -> closing.
