it does seem too "out there". if i were to guess you have a nullpointer in one of your events.

A java.lang.NullPointerException is a pretty common problem, you need to show us your code if we are to help you in any way.
Also in the StackTrace that you have pasted, highlight to us the lines which belong to your ".java" file.
