This has some pretty severe restrictions and some more that aren't
mentioned (overriding getUpdateCount(), not using the V2 protocol which
has nothing to do with JDBC2/3).  We've implemented generated key
support in CVS for the upcoming 8.4 release that is more robust, but makes
some other tradeoffs (returning all columns rather that just a single
key).  Could you test this out in your application?
