I am getting the same error with my development server connected to either the
live or dev database. Except my error says :

java.util.EmptyStackException
at java.util.Stack.peek(Unknown Source)
All I am doing is a cfudate from a form page but I can get query results back
though. The funny thing is I have a live server that connects to the live DB
perfectly fine with the same code. So the code is not the error it seems.
What I think is there is something in the CF server that is not configured
correctly but I can't figure it out. Please help for both of us.
