Description Vladimir Voskresensky 2010-11-22 12:29:36 UTC 
there is CR6992581 in bugster against Studio IDE from custumer:
----------
On my system, it's taking 3.5 minutes before the file chooser comes up.
- I supplied --userdir to a local disk.  (The userdir.java did not previously
exist).
- The project I want to open is on the local disk.
- The CWD is on the local disk.
Why does the file chooser default to my home directory?  Why does it take so
long to come up?
-------------
I think it does not matter if I have any "broken" or "slow" links in my
home directory. The point is that the IDE should NEVER look inside my
home directory unless I explicitely told it to look there. There is 
only one subdirectory inside my home that the IDE can use - it is
${HOME}/.sunstudio
Also, the IDE should NEVER use AWT thread to perform any I/O operations.
------------
Comment 1 Vladimir Voskresensky 2010-11-22 12:31:57 UTC 
100% reproducible testcase:
- in home dir create broken link to NFS system which is not reachable now 
- try to open Open Project dialog and it takes minutes to populate with content.
(or just put Thread.sleep(2000) in updateCompletions method)
Comment 2 Ondrej Vrabec 2010-11-22 13:12:34 UTC 
1) why does the project chooser open in your home dir? Looking at
http://hg.netbeans.org/core-main/file/0f6ce06434f3/projectui/src/org/netbeans/modules/project/ui/ProjectChooserAccessory.java#l485
and
http://hg.netbeans.org/core-main/file/0f6ce06434f3/projectui/src/org/netbeans/modules/project/ui/OpenProjectListSettings.java#l328
i guess you should complain in projects

2) calculating file completion in AWT - i'll try to fix that
Comment 3 Ondrej Vrabec 2010-11-22 15:11:42 UTC 
fix: #1555a6df1616 - http://hg.netbeans.org/core-main/rev/1555a6df1616
Comment 4 Ondrej Vrabec 2010-11-22 15:12:37 UTC 
i hope the fix deals with both problems, let me know if it helps
