С учетом следующего кода:
class A extends Actor {
def act() {
loop {
reactWithin(1000) {
case _ => println("A Message")
}
}
}
}
и
class B extends A {
val test = Actor.actor {
loop {
reactWithin(1000) {
case "B" => println("B Message")
}
}
}
}
Создание экземпляра B val t = new B()
вызывает следующее исключение:

Может ли кто-нибудь объяснить мне, почему это так? :)
