给出以下代码:

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

和

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

创建B的实例会val t = new B()引发以下异常:
