default value for Accept-Language?

I have a suggestion if the browser does not provide an Accept-Language variable then give a default value.... which would be better then the 500 error I get.

This probably never happens for the majority if not all browser out there but I ran into this will trying to create a JMeter script to load test Maverick.  I was able to fix the issue by adding an Http Header Manager to JMeter.

The mod would be made in LanguageShuntFactory.getView in the first line of code...
