I've no way to change this design in my application. The app has
thousands "select and forget" statements with deep loops in different
classes.

But the prepareStatement is in a central wrapper, easy to change. Only
the source code compatibility is a problem. It should work with Java 1.4
and 1.5 (and jaybird 1.5.x and 2.x) - so I need reflection and a
driver version test. :-/

Thank you for your help and best regards,
Josh.
