When I open Matlab, I always get the following lines

Can someone tell me where they're coming from? And if possible, how to fix it?

This is related to a Java issue, for which there is information at http://bugs.java.com/bugdatabase/view_bug.do?bug_id=7075600
You can have a look on the similar thread mentioned above. Best would be to try to upgrade your MATLAB version
