我是新的akka，并试图做以下简单的例子：

public static void main(String[] args){
        Config cf = ConfigFactory.parseString(" bounded-mailbox {\n"
            + "  mailbox-type = \"akka.dispatch.NonBlockingBoundedMailbox\"\n"
            + "  mailbox-capacity = 1000\n"
            + "}");
        ActorSystem system = ActorSystem.create("MySystem", cf); ActorRef                  
        myActor = system.actorOf(Props.create(MyActor.class).withMailbox("bounded-mailbox"), "myactor");
        for(int index = 0; index<=100; index++) {
            myActor.tell(index, myActor.noSender());
        }
        try {
            Thread.sleep(120000);
        }catch (Exception exc){}
   }

MyActor.class -是一个简单的actor类，用于打印接收到的消息。
当我运行这个时，我得到以下错误：

Caused by: java.lang.IllegalArgumentException: Cannot instantiate MailboxType [akka.dispatch.NonBlockingBoundedMailbox], defined in [bounded-mailbox], make sure it has a public constructor with [akka.actor.ActorSystem.Settings, com.typesafe.config.Config] parameters

有什么想法吗？我正在运行与akka-actor_2.10 -2.3.7
