Matlab R2012b - Java Exception, Error Starting Desktop
显示 更早的评论
Hi folks,
I updated my Matlab R2012b on my Ubuntu system (11.04). The installation process went smoothly, but when I want to start Matlab, I encounter the following error, before the programm shuts down.
java.lang.runtimeexception: std::exception for "matlab.desktop.currentfolder.GroupColumn": Cannot write to the level specified even after multiple times of retry. It'S mostly due to no write permission.
It seems to be a rights or ownership problem because if I start Matlab with the sudo command, it starts up fine. I could not find the libary or the file Matlab tries to edit. Any ideas?
thanks
Bart

Same thing happens to me on a macbook. Same exception, exception disappears when starting matlab using sudo. Any help appreciated!

Most likely you don't have write permissions on your preferences directory. You can determine the location of the MATLAB preferences folder by running the PREFDIR command at the MATLAB prompt. If for some reason you're unable to fix the permissions, you can try changing the prefs directory location:

following command could also solve your issue:
sudo chmod -R a+rw ~/.matlab
You need option "-R" here to apply the change to all of its sub-folders too.
Hope it helps. :-)

Correct solution for MATLAB R2013a on ubuntu 12.04.2.
I tried to start via terminal a second instance of matlab with a different user. Perhaps this messed up my profile...

Thanks! Correct solution for MATLAB R2012b on Mac OS X 10.9.4. I tried to run MATLAB from terminal using 'sudo' command. After that I was getting the same error. This fixed the problem.
