Quick update:
another test i ran this time round is that the cluster application is left
running (i.e. Play 2.3 + Akka 2.3.2) and i had a client connect to the
clustered application using Play 2.2 + Akka 2.2.3 and this time round i am
able to connect to the router and send messages to the environment running
Play 2.3 + Akka 2.3.2
Will continue to dig to see what's going on here.
