Scala Remote Actors stop client from terminating - scala

Question

I am writing a simple chat server, and I want to keep it as simple as possible. My server listed below only receives connections and stores them in the clients set. Incoming messages are then broadcasted to all clients on that Server. The server works with no problem, but on the client side, the RemoteActor stops my program from termination. Is there a way to remove the Actor on my client without terminating the Actor on the Server?
I don't want to use a "one actor per client" model yet.
import actors.{Actor,OutputChannel}
import actors.remote.RemoteActor
object Server extends Actor{
val clients = new collection.mutable.HashSet[OutputChannel[Any]]
def act{
loop{
react{
case 'Connect =>
clients += sender
case 'Disconnect =>
clients -= sender
case message:String =>
for(client <- clients)
client ! message
}
}
}
def main(args:Array[String]){
start
RemoteActor.alive(9999)
RemoteActor.register('server,this)
}
}
my client would then look like this
val server = RemoteActor.select(Node("localhost",9999),'server)
server.send('Connect,messageHandler) //answers will be redirected to the messageHandler
/*do something until quit*/
server ! 'Disconnect

I would suggest placing the client side code into an actor itself - ie not calling alive/register in the main thread
(implied by http://www.scala-lang.org/api/current/scala/actors/remote/RemoteActor$.html)
something like
//body of your main:
val client = actor {
alive(..)
register(...)
loop {
receive {
case 'QUIT => exit()
}
}
}
client.start
//then to quit:
client ! 'QUIT
Or similar (sorry I am not using 2.8 so might have messed something up - feel free to edit if you make it actually work for you !).
