Scala Akka Alignment

[Joseph Mansigian]

I am trying to use scala 2.11.8 and akka 2.4.9 for remoting.  Not sure if these versions are compatible.  I noticed that there is an akka jar with scala which is confusing to me since I already hava akka jars on the classpath.  When I run code  I am getting:

  java.lang.NoSuchMethodError: akka.util.Helpers$.toRootLowerCase(Ljava/lang/String;)Ljava/lang/String;

Have the jar with some version of akka.util.Helpers$ on the classpath but apparently this version does not have the method cited in the error message.  Anyone recognize what is happening?  Source, classpath, directory structure, stacktrace, etc available on demand.   Thank you for helping.

You can see which version of Scala an Akka artifact is released for by looking at the artifact names:

http://search.maven.org/#search%7Cga%7C1%7Ca%3A%22akka-remote_2.11%22

So as you see, it's released for 2.11.

That you're talking about jar files makes me thing you're mixing different akka versions... That's not supported, make sure it's all the same version of Akka.

Also, why not the latest version 2.4.10?
