ISRuntimeException is not working as expected in IS 61Modeler integrations

Hi All,

     We are using IS 6.1,Broker,Modeler for our integrations. 

I have a trigger set up with retires : 5 and retry interval:10 mins.
When the target system is down we would like to reque the document in broker after these 5 retries by throwing ISRuntimeException.

When I try to test the integration - our Modeler last step is throwing immediate runtime exception - I never see any serverlog or errorlog that trigger is retrying 5 times in above specified times.

If I use the same logic without modeler - it is working for me. Do I need to set up different way in Modeler?.
