Ah. Thanks for that very enlightening and helpful explanation - I really
appreciate your taking the time.
It's interesting that the JDK presents these issues to driver
developers, but I see how there's no easy way around it given that Java
offers no way to declare default implementations of methods in
interfaces (iow: no multiple inheritance) so the JDBC interfaces can't
provide stubs.
Argh, if only Java had scope-based object lifetime with prompt
finalization (think C++ "stack-based" objects) and multiple inheritance...
