Timer on Border of Activity

The timer is triggered 60 seconds after Activity A starts. When the timer fires, Activity A is stopped because it is located on its border. If the timer fires, then the transition to the Stop node is traversed. This causes this process instance to be terminated with a status of Timeout.
