Video file - step to reproduce

Description of problem:
If the process contains a parallel gateway with probabilities (x,y) of outgoing flows, which are set to x:y where x + y < 200 && x <= 100 && y <= 100, then the simulation engine starts less instances (for example 60:40 - starts 2 instances instead of 10).

If probabilities of outgoing flows are set to 100:100 then the number of started instances is right.


Version-Release number of selected component (if applicable):
6.0.0 BPMS ER3


Steps to Reproduce (see attached video):
1. create a process (see attached image of BPMN2)
2. set the probability of the flow from gateway to "h2" to 60
3. set the probability of the flow from gateway to "sss" to 40
4. run simulation 10 instances, 10 minutes

Actual results:
Number of instances for each activity is 2 (see attached screenshot)
Table for path:
------------------
|Path1       | 2 |
|Other Paths | 8 |
------------------

Expected results:
Number of instances for each activity is 10 (see attached screenshot)
Table for path:
-------------------
|Path1       | 10 |
|Other Paths |  0 |
-------------------

I believe that a probability parameter is useless for parallel gateway. I think that engine should ignore such parameters.
