If you notice any, please report them in the projects bug-tracking area at: http://sourceforge.net/tracker/?group_id=233279&atid=1089227
Please be specific with bug reports so they can be properly attended to. Vague reports will not be attended to unless the error is quite obvious.
Include some code or a description of the conditions you encountered the bug in so it can be reproduced. The more detail, the higher the chance of it being fixed quickly.
NotImplemented exceptions are not bugs. They are features that have not been fully implemented yet and will vary for each release. This technique of dealing with unfinished areas is part of the JDBC specification for drivers [http://java.sun.com/products/jdbc/driverdevs.html].
If you would like to see a particular feature implemented, please make a feature request at: http://sourceforge.net/tracker/?group_id=233279&atid=1089230
