How to Debug java exceptions?

I got this error in command window, but I have no clue where the error in code is.

Enabling the option "Stop on errors" also doesn't help. Anyone has a better idea?

Song - is this error message repeatable? If so, what are the steps involved in creating the problem?

You have tagged this question with gui and uitable so does the problem occur when the user manipulates (edits or selects) a cell in the uitable of your GUI? Or the problem manifest in some other way?
