Eclipse debugging has dialog box: Exception processing async thread queue java.lang.NullPointerException

Question

I am facing a problem while debugging in Eclipse 3.4.2. I keep getting pop-up Exception processing async thread queue java.lang.NullPointerException

Does anyone know what the exact problem is?

Thanks

The problem was with the expressions watching while debugging. If those old expressions are not removed, it just keeps evaluating them and since they don't exist for current program, they keep throwing null pointer exception.
