## Introduction

Starting with Scala 2.11.0, the Scala
[Actors](http://docs.scala-lang.org/overviews/core/actors.html)
library is deprecated. Already in Scala 2.10.0 the default actor library is
[Akka](http://akka.io).

### Step 5 - Moving to the Akka Back-end

At this point user code is ready to operate on Akka actors. Now we can switch the actors library from Scala to
Akka actors. In order to do this configure the build to exclude the `scala-actors.jar` and the `scala-actors-migration.jar`
and add the *akka-actor.jar*. The AMK is built to work only with Akka actors version 2.1 which are included in the [Scala distribution](http://www.scala-lang.org/downloads)

and to include *akka-actor.jar* and *typesafe-config.jar*. The AMK is built to work only with Akka actors version 2.1 which are included in the [Scala distribution](http://www.scala-lang.org/downloads)
and can be configured by these [instructions](http://doc.akka.io/docs/akka/2.1.0/intro/getting-started.html#Using_a_build_tool).

After this change the compilation will fail due to different package names and slight differences in the API. We will have to change each imported actor
from scala to Akka. Following is the non-exhaustive list of package names that need to be changed:

scala.actors._ -> akka.actor._
scala.actors.migration.ActWithStash -> akka.actor.ActorDSL._
scala.actors.migration.pattern.ask -> akka.pattern.ask
scala.actors.migration.Timeout -> akka.util.Timeout
