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?

I have a flow: start -- User Task - Rule Task - User Task - Action -
end.
I complete the 1st User Task, next the rules which are part of the
RuleFlowGroup in the Rule Task fire correctly, then I complete the
next User
Task. However, my final action node is never reached and the
processInstance
never completes.
Here is my Rule Flow:
