Summary: strange ArrayIndexOutOfBoundsException

Initial Comment:
I get the following error sometimes whenever I am working. I am not sure what causes it. It doesn't seem to create any problems for me so far, but it isn't comforting knowing DrJava is throwing errors at me when I am trying to focus on my own code.
