Jason van Zyl commented on MNG-2899:
------------------------------------

Dan, I'm sure this is being caused by the same thing that caused the last problem in yoko. I'm sure we can track it down and fix it. For some reason artifact info is not making it though when ${version} is being used.  From a brief look it seems that because depMan was never used before consistently the null makes it through in the process and just propagates because we don't check it and just assume it will be there. It resolves to an empty string which is no longer null and makes it through the gate.
