The original pgbench was actually based on an older test named JDBCbench.
That code is kind of old and buggy at this point. But with some care and
cleanup it's possible to benchmark not only relative Java performance with
it, but you can compare it with pgbench running the same queries on the
same tables to see how much overhead going through Java is adding.
Original code at http://mmmysql.sourceforge.net/performance/ , there's
also some improved versions at
http://developer.mimer.com/features/feature_16.htm
I'm not sure if all of those changes are net positive for PostgreSQL
though, they weren't last time I played with this.
