AbstractMethodError с Akka 2.3.3 и Play 2.3.1

Question

Я разрабатываю приложение Scala с использованием Play, Akka и ReactiveMongo. Вот конкретные библиотеки, которые я использую...

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

Когда мой код выполняет асинхронный вызов коллекции MongoDB, я получаю следующее исключение:

java.lang.AbstractMethodError

Другие сообщали об этом исключении при использовании Akka 2.3 с Play 2.2, но ничего с версиями, которые я использую. ReactiveMongoPlugin успешно загружен.
