Looks like kris found the real cause why you didn't get the latest mvel 
snapshot as needed:
   
https://github.com/droolsjbpm/jbpm/commit/23339ee970843066e7eaa8e625c4a096edc562a6#L1L66

I agree we should strongly prefer not to use mvel snapshot's if we can 
avoid it (which we can't for this release :( ).
