In my experience you don't want to upgrade the jars that come with
Pentaho. If it is not the versions that they come with the chances are
that things will not work. The JDBC driver might be upgradeable, I
believe we downloaded that by ourselves.
Also we had a much better experience with Jasper (free version) then
Pentaho (free version).
