Playframework 2.0 Akka 2.3.3和Play 2.3.1的AbstractMethodError

我正在使用Play、Akka和ReactiveMongo开发一个Scala应用程序。以下是我正在使用的特定库

org.scala-lang#scala-library;2.10.4
com.typesafe.play#play_2.10;2.3.1
com.typesafe.akka#akka-actor_2.10;2.3.3
org.reactivemongo#reactivemongo_2.10;0.10.0

当我的代码对MongoDB集合进行异步调用时，会出现以下异常：

java.lang.AbstractMethodError

其他人在将Akka 2.3与Play 2.2一起使用时报告了此异常，但在我使用的版本中没有任何异常。已成功加载ReactiveMongoPlugin。

升级到ReactiveMongo 0.11.0\u快照似乎可以解决此问题。我强烈建议使用每个库公布的依赖项（除非您确定二进制兼容更新）。在这种情况下，reactivemongo_2.10依赖于Akka 2.2.1（它与2.3.x不兼容）。手动混合版本很可能会导致此类错误。我对akka 2.3.7和reactivemongo 0.10.5-akka23也有同样的问题。你找到解决办法了吗？
