runtime error - akka.dispatch.Dispatcher IllegalStateException in scala.concurrent internal callback -

i'm trying use akka 2.4.12 play 2.5.4 (scala 2.11.7). i'm injecting actorsystem using

guiceapplicationbuilder().injector()

with

system = injector.instanceof[actorsystem]

or

@inject()(implicit val system: actorsystem)

to instance of actorsystem. i'm using these 2 mechanisms (the first 1 in scala objects , second 1 in controllers) substitute deprecated default akka actor system (akka.system). can't understand why error:

maybe there errors in code initialize main actors can't figure out where:

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 1 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 application log.
