java.lang.VerifyError函数的不兼容参数

Question

sbt run对于我编写的Spray示例应用程序,我收到一个奇怪的错误,它编译得很好,我只在我的个人计算机上得到错误,因为它在另一台计算机上工作正常.

这是我认为的相关来源,它是Spray示例代码的模板代码,但我不认为这是原因.

package spray.examples

import akka.actor.{ActorSystem, Props}
import akka.io.IO
import spray.can.Http

object Boot extends App {

  implicit val system = ActorSystem()

  // the handler actor replies to incoming HttpRequests
  val handler = system.actorOf(Props[DemoServiceActor], name = "handler")

  IO(Http) ! Http.Bind(handler, interface = "localhost", port = 8080)
}

这是堆栈跟踪

如评论中所示,这可能是一个classpath问题,但我不知道如何调试.巧合与否,这种情况发生在我从Mac OS X Java 6升级到Java 7之后,我在两台机器上都安装了Java 7.任何见解将不胜感激.

如果这可能会有所帮助,这里是classpath转储sbt console,对于编译和运行时来说都是一样的

如果有人关心尝试使用Java 7进行全新编译,那么请sbt run随意从回购中获取它.

不幸的是,1.2-M8与Akka 2.2.0 final不兼容.要么使用Akka 2.2.0-RC1,要么升级到最近的夜间喷雾1.2.

更新:此外,到目前为止,最终版本已经发布,因此您可以将1.2.0版本与最新的Akka 2.2.3一起使用.
