/**
 * A {@link NonBlockingVoidMuleEvent} represents a void return, but in contrast to {@link org.mule.VoidMuleEvent}
 * while the return up the stack is void, an asynchronous response is expected.  Because Mule supports both blocking and
 * non-blocking then it is the return of this event instance that signals that a callback is to be expected.
