jRuby error - can't modify frozen array

I keep getting this error in my App, no matter what I try to fix. "can't modify frozen array"

Any idea what could be possibly wrong here? I am running a jRuby (1.6.2) app on Torquebox (1.0.1) on my local Ubuntu (10.04) machine. Here is a complete stack trace

If you get the error during startup, chances are big you're actually trying to redefine a frozen array in an initializer (could be as simple as redifining ABBR_DAYNAMES). If the application can run under MRI you could try that, since it gives you verbose warnings about this.

If there's nothing in your initializer, then it might be a gem that you included in your application. Try taking out gems one by one and see what the result is.
