> When a vertex gets invalid event, the state machine will be transited by InternalErrorTransition.
This transition prints this and adds it to dag diagnostic: 
> {code}
> ("Invalid event " + event.getType() + " on Vertex " + vertex.getLogIdentifier()
> {code}
> But variable event here is V_INTERNAL_ERROR event instead of the event that caused V_INTERNAL_ERROR.
V_INTERNAL_ERROR is not the invalid event, the original event is.
