Mike did an API change to fix the MVEL performance issues and releases a
snapshot for us to try. I then had to update Drools and jBPM to work
against this new api. There was an issue with jBPM's pom that meant it
wasn't seeing the latest MVEL snapshot and thus wouldn't compile. Kris
is aware and fixing, if not fixed already.
