Actor creation error in akka

trying to create an actor in akka and call its receive function. I keep getting this error.

CODE TO CREATE AND CALL ACTOR RECEIVE.

val system = ActorSystem("messagespreading")
var NetworkBuilderObj:ActorRef= system.actorOf(Props[NetworkBuilder]) 
NetworkBuilderObj ! test

When you get an exception occurring in third-party code, you need to look to see if there is a Caused by. In this case it says 

Caused by: java.lang.IllegalArgumentException: n must be positive
 at java.util.Random.nextInt(Random.java:250)
 at scala.util.Random.nextInt(Random.scala:65)
 at NetworkBuilder.(pastry.scala:431)

so there is the error - it has nothing to do with the code you posted per se.
