No, I think you're misunderstanding. An ActorSelection is (effectively) an
*address*. It will never be null -- by and large, Akka tries to avoid
nulls. You can always try sending a message to it, which means "send this
message to the Actor that has this address"; that will fail to be delivered
if the address doesn't point to an actual Actor.
