Are you working in non-managed case? If yes, than what prevents you
to switch your code from auto-commit to non-autocommit and use
explicit con.commit()/con.rollback() when you finished working with
the database? I think that using the FBLocalTransaction is not the
best way to control the JDBC transactions in the non-managed scenario.
