Given that Java Hotspot runs at approximately the same speed as natively 
compiled code for the most part already, how much more speed could you 
conceive of getting?

It supports "most" of the libraries and only "some" of the 1.5 "additions" 
(whatever they mean by that).  Apparently your JDBC driver library isn't among 
"most" of the ones supported.
