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

[Antoine Toulme]

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
