ActorSystems created via OsgiActorSystemFactory(ctx).createActorSystem fail to load akka.event classes unless bundle imports akka.event package.

Specifically, when using OsgiActorSystemFactory(ctx).createActorSystem(Some("name")) in a bundle who does not import akka.event, I get the following exception:

Caused by: akka.ConfigurationException: Could not start Event Handler due to [9962cf05-ca32-48e6-9643-417e51494acfakka.ConfigurationException: Event Handler specified in config can't be loaded [akka.event.Logging$DefaultLogger] due to [java.lang.ClassNotFoundException: akka.event.Logging$DefaultLogger from bundle 19 (my-bundle-name)]]

This is using Scala 2.10.0-RC2 with Akka 2.1.0-RC2 on Equinox 3.7.
