Description

When a Task is created, RuntimeManager's identifier is persisted as Task's deploymentId. Later on, when TaskService.complete() is called, ExternalTaskEventListener picks up the RuntimeManager from RuntimeManagerRegistry using the Task's deploymentId as a key. If the RuntimeManager is not registered in RuntimeManagerRegistry at that time (for example, after reboot), it fails with NullPointerException. It's okay to fail but it's better to have a meaningful error message.
