The problem is multi-posting. Please do not do that. As a service, I have
corrected the multi-post (by cross-posting) and repeated the question for
someone to answer. This way the conversation will not be fragmented across
multiple groups.

Please read the FAQ in clj.programmer, and the links to which it points. It's

I don't recognize any of lines in your stack trace as coming from
Derby. Why do you think that Derby is the cause?
