Thanks Mike for pointing out there is a way to print out the queries. From
derby.log, I can see the program issued an unexpected commit while trying
to mimic a DB2/Oracle feature. It is not a derby problem.

Please respond to Re: Rollback problem
"Derby
Discussion"
This is going to show my predjudice about the recovery code, but at
least as described this seems so simple that I think there must be
something tricky going on.
To diagnose the issue you should enable the property to print all
queries to the derby.log, so that we can see if there is an unexpected
commit. If you can't find appropriate documentation on list or in docs
let the list know.
Definitely check how you are setting autocommit and make sure same
connection is used to do first insert and subsequent inserts - as
autocommit can be set on a per connection basis. Maybe good to describe
how you are turning autocommit off.
