Is there any chance that Connection.commit() is called from some third

Can you include complete stack trace?

Without stack trace - no.

It does. But JayBird is a little bit paranoid in implementing
specification. For example, specification does not allow to call
commit() in autocommit mode, so JayBird will not allow it under no
circumstances (at least should not :).

Please, post your stack tarce, we should be able to tell you more.
