title: "Dead letters encountered" as soon as actors are placed into router
body: <p>Here's what I'm finding, and for the life of me I can't navigate to the reason.  I'm creating "printer" actors that basically either do nothing, or print a message based on the type of message they receive.</p>
  
  <pre><code>class Printer extends Actor {
      def receive = {
          case m: SomeMessage =&gt; println( m.text )
          case _ =&gt;
      }
  }
  </code></pre>
  
  <p>I'm creating several of these actors:</p>
  
  <pre><code>val actor4 = system.actorOf(Props[Printer], "t-4")
  val actor5 = system.actorOf(Props[Printer], "t-5")
  val actor6 = system.actorOf(Props[Printer], "t-6")
  </code></pre>
  
  <p>and throwing them into a vector:</p>
  
  <pre><code>val routees2 = Vector[ActorRef](actor4, actor5, actor6)
  </code></pre>
  
  <p>I'm doing the above so that I can throw them into a router (and they will be under the router's control).  When I run the spec up to this point I'm not having any issues.  As soon as I place them in a router and run the spec I'm having problems.  Here's the router:</p>
  
  <pre><code>val router = system.actorOf(Props[Printer].withRouter(
      BroadcastRouter(routees = routees2)), "router-to-transformers")
  </code></pre>
  
  <p>Now when I run the spec I have all sorts of dead letters...</p>

  <p>For the life of me I can't figure out what is going on here.  I've added a link to a snippet of the test.  The numbering, in the snippet, is weird because I've cut a bunch of different attempts that were commented out so as to not clutter the snippet.  I'm focused on this dead-letters issue because I feel like when I added a more actors and actually started passing messages around, things weren't getting delivered...

  <p>It's worth calling out that these actors are local.  I've read something about actorFor being depreciated and I'm wondering if that is being used and is partly what is causing my issues?  There are so many moving parts here though and not a lot of stable, COMPREHENSIVE, documentation.  Any help would be greatly appreciated.</p>
