问题描述
我正在尝试将Scalatra与AkkaSupport和新推出的（2.2.0 RC2）GZipSupport一起使用。它失败了，在提交错误报告之前，我试图找出是否做错了什么。该代码是默认的Scalatra / Akka示例，包括GZipSupport特性：
I'm trying to use Scalatra with AkkaSupport and the newly introduced (2.2.0 RC2) GZipSupport. It fails and I'm trying to figure out if I'm doing something wrong, before I file a bug report. The code is the default Scalatra/Akka example, including the GZipSupport trait:
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>
}
}
}
我得到以下内容堆栈跟踪：
I'm getting the following stack trace:

这是一些错误还是我错过了一些东西？
Is this some bug or am I missing something? Thanks in advance!
