Scala主体例外"に反応チャンネルに属するその他の俳優"

Question

さらに次のコード:

class A extends Actor {
  def act() {
    loop {
      reactWithin(1000) {
        case _ => println("A Message")
      }
    }
  }
}

や

class B extends A {
  val test = Actor.actor {
    loop {
      reactWithin(1000) {
        case "B" => println("B Message")
      }
    }
  }
}

創造のインスタンスB val t = new B() スローでは、以下の例外:

が誰かに是非ご教授下さい私はなぜですか？:)

内部の俳優。俳優のブロックでは、参照しなければなりません。ようなものが反応し、reactWithinの"自己"変数はこのように:ます。reactWithin(1000).これらの方法から継承された親クラスです。
