Matlab Java Errors?

[daviddoria]

I just installed matlab on Fedora 9. When I run it, i get the errors below. If I just ignore the errors, everything seems to work fine. Has anyone else experienced this?

Below is the output:

I have the same problem on a FC9 64bit machine and have reported it. See below thread.

You may have to allow sloppy locking in SE Linux but matlab will run despite the errors. I recommend switching off compiz for more stability in the X windows system.

You might also run into printing problems from matlab. The print dialog will not come up but you can print from the matlab command line.
