AkkaSupport と新しく導入された (2.2.0 RC2) GZipSupport で Scalatra を使用しようとしています。失敗し、バグレポートを提出する前に、何か間違っているかどうかを調べようとしています。コードは、GZipSupport トレイトを含む、デフォルトの Scalatra/Akka の例です。
package com.myapp
import _root_.akka.dispatch._
import _root_.akka.actor._
import org.scalatra._
import org.scalatra.akka.AkkaSupport
class myappServlet extends ScalatraServlet with AkkaSupport with GZipSupport {
implicit val system = ActorSystem()
get("/"){
Future {
<html><body>Hello Akka</body></html>
}
}
}
次のスタック トレースを取得しています。

これはバグですか、何か不足していますか? 前もって感謝します！
