Java exception with OS X Yosemite seems to occur constantly

MATLAB has been dumping out red text that looks like some kind of Java issue. Generally, this isn't a serious problem, it's just incredibly annoying when trying to diagnose scripting problems since I have to scroll through 50 lines of red text to get back to my output.

This is what my error looks like--

Without any further information on what you are trying to do (your code, for instance, would help a lot), it is impossible to answer this question (unless you found that Yosemite is the origin of the problem as you seem to insinuate in your question).

my best guess: your file is corrupted, Java does not like it and throws some errors.

I am also having this issue. This exception (or one very similar) is thrown when doing most anything. For instance: the exception occurs if I clear variables on the command line by evoking 'clear'. It also occurs if I attempt to open the variable editor by double clicking a variable in my workspace, it also occurs when evoking 'version'. I did not have this issue prior to upgrading to Yosemite.

This is clearly a MATLAB exception and has nothing to do with an individual user's code. The exception is a 'NullPointerException' exception in the WindowsWidgetFactory class with is mathworks MATLAB code.

There is a patch here http://www.mathworks.com/support/bugreports/1098655 which addresses this issue.

Sadly I'm on 2011a and that won't work for me. It is very annoying though
