How is it possible to fire the same intermediate timer event multiple times

[sunblocker]

I modeled a loop within my process that should periodically check, whether or not the proper information has been put into the DB (polling mechanism). For this reason, I have connected a start event with a intermediate timer event (Duration PT5S), the timer event is connected with a service task (for the check), the service task is connected with a XOR gateway (complete yes/no). One path of the XOR goes back to the timer event.

However, the timer seems to be fired only one time. I guess the counter has not been reset by the process engine. Is there a way to realize that?

And the process instance is waiting in the timer indefinitely?
Could you create a unit test and create a JIRA if this is the case?

Best regards,

The problem is that the timer will only wait at the first time. When the timer is triggered again it does not wait at all.
I attached the BPMN file.
