> The Java SE 7 try-with-resources feature can cause problems with
> AutoCloseable objects like java.sql.Connection. You must be careful when
> writing portable code which declares Connections in the initializers of
> try-with-resources blocks, because Derby raises an exception if you try to
> close a Connection with uncommitted work in-flight.
> Changing Derby's Connection.close() to always commit in-flight work (and not
> raise an exception) would create backward compatibility issues, but we do not
> know yet how serious these issues would be, owing to a lack of data.
> Rather than change Derby's behavior now, we should document how Derby's
> Connection.close() behaves and describe the portability issues involved in
> declaring Derby Connections in try-with-resources initializers.
