[rules-users] ProcessInstance Does Not Complete With User Task and Rule Task

[Kris Verlaenen]

Hi,

I executed the process you provided and do not seem to have any problems
with it.  This is the output:

### Starting process ###
### Completing second work item ###
Finished!!!

Could you try your code with the latest snapshot releases?
