Is it random? If not, could attach zipped Userdir/config/Windows2Local/Modes?

Could you attach zipped Userdir/config/Windows2Local/Modes to this bug? Thank you for report.

pbadams Modes directory ZIP
Comment 6 Jiri Skrivanek 2008-05-22 11:11:51 UTC 
Thank you for the attachment. But I am still not able to reproduce the problem. Please, could you write down detailed
step-by-step description what you did before exception appeared? And also zipped Userdir/config/Windows2Local/Modes at
the time of exception would be helpful. Also please, make sure you use the latest 6.1 build.
Comment 7 pbadams 2008-05-23 06:29:38 UTC 
I've not encountered this problem for a while and am unable to reproduce at this time. I have been using a project located on a USB Memory stick, otherwise 
this is a regular Netbeans installation. 

If I encounter the exception again I will attempt to script the actions required to reproduce and upload a ZIP of my Modes folder.

Regards, Paul.

Comment 9 Jiri Skrivanek 2008-05-29 09:45:51 UTC 
Thanks to joshis I found out what happens. If the IDE is run with root privilegies, files under
Userdir/config/Windows2Local/Modes are created or modified with root ownership. Then if the IDE is run with user
privilegies, the files cannot be changed and exception is thrown. I changed the code to not throw such confusing exception.

Comment 10 Lukas Hasik 2008-05-29 09:54:12 UTC 
joshis, could you verify it when a build with the fix will be available? Thank you.

I'm marking as 61 patch2 candidate
