Hi, I'm trying to use akka 2.4.12 with play 2.5.4. I'm injecting
ActorSystem using "*GuiceApplicationBuilder().injector()*" with "system =
injector.instanceOf[ActorSystem]" or "*@Inject()(**implicit val system:
ActorSystem**)*" to get an instance of ActorSystem. I'm using these two
mechanisms (the first one in the scala Objects and the second one in
Controllers) to substitute the deprecated default akka actor system
(*Akka.system).
*I can't understand why I get this error:

Maybe there is some errors in this code to initialize the main actors:
object ActorUtils{
val injector = new GuiceApplicationBuilder().injector()
val configuration = injector.instanceOf[Configuration]
val messagesApi = injector.instanceOf[MessagesApi]
val messages = messagesApi.preferred(Seq(Lang.defaultLang))
// val injectorGuice = Guice.createInjector(
// new ConfigModule(),
// new AkkaModule()
// )
// import net.codingwell.scalaguice.InjectorExtensions._
implicit val system = injector.instanceOf[ActorSystem]
val adminAddress = configuration.getString("emailer.adminAddress").get
// ----- Top-level actors with just one incarnation -----
val userDao = injector.instanceOf[UserDAO]
val supervisor =
system.actorOf(SupervisorActor.props(), "supervisor-actor")
val taskDispatcher =
system.actorOf(TaskDispatcher.props(supervisor), "task-dispatcher")
val responseHandler =
system.actorOf(ResponseHandler.props(supervisor, taskDispatcher),
"response-handler")
val taskStateActor =
system.actorOf(TaskStateActor.props(supervisor, responseHandler,
taskDispatcher), "task-state-actor")
}
I attached the application log. Thank you.
