[rules-dev] Guvnor MVEL problem on Guvnor master?

We really only care about jBPM, and as of now, we build it against M2. M2
was depending on mvel snapshot, so it started breaking when new snapshots
were introduced.

I am not a big believer in snapshots for coordinating complex products like
Drools with many moving pieces. I voiced this to Mark in the past, and I
need to discuss this with you when we have time.

Thanks,

Antoine
