abhijithumbe opened a new issue, #7235:
URL: https://github.com/apache/incubator-kie/issues/7235
An intermitent NullPointerException occurs when a Terminate End Event
attempts to cancel an active CallActivity in a parallel execution flow.
Process contains a Parallel Gateway that forks into three concurrent
branches:
CallActivity: Invokes the scripts.bpmn subprocess.
Task1: User task.
Task2: User task followed by a Terminate End Event.
When Task2 is completed, the process reaches the Terminate End Event, which
attempts to terminate the entire process instance by cancelling the remaining
active branches, including the CallActivity and Task1.
