problem. AWT thread was blocket for long time.

Comment 5 David Strupl 2003-01-14 14:08:24 UTC 
Seems like a problem in FolderList - virtually endless refreshing of
the list.
Comment 6 David Strupl 2003-02-26 10:55:19 UTC 
This is very hard to reproduce. With enabled logging
(by passing -Dorg.openide.loaders.FolderList=-1 command line param) it
shows that when a lot of folders are scanned the whole process blocks
AWT thread.

It is hard to get it to a state when this is a problem --> making it P3.
Comment 7 Marian Mirilovic 2003-03-13 13:43:03 UTC 
Changed owner David S. -> David K.
Comment 8 David Konecny 2003-04-30 10:47:01 UTC 
Changing TM to "FUTURE" which is more appropriate, because at the
moment I do not plan to fix this issue for next version. Let me know
if you disagree. I'm open to change the plan.
Comment 9 Jaroslav Tulach 2004-08-04 17:15:07 UTC 
The AWT thread in the tread dump seems to be blocked by loading of
annotation types, when editor's menu is constructed. The only solution
is either to construct the menu without knowing the list of
annotations or to pre-compute the list. It is hard to make FolderList
faster, I would say impossible. 

Btw. maybe this is no longer problem for promo-D as I saw the editor
menu to be made significantly smaller.
Comment 10 Miloslav Metelka 2004-08-09 14:11:15 UTC 
This is no longer an issue as the "Margin" submenu was removed from
the editor's context menu according to the UI spec
