Hi all,

I'm constrained to Scala 2.9.2 and Akka 2.0.5 on my project and I am 
confused how unhandled messages are intended to be logged.

It seems that in order to get any form of logging, the receive method must 
use the LoggingReceive wrapper. This then shows handled and unhandled 
messages in the logs thanks to akka.actor.debug.receive. This is a bit of a 
pain as I'd rather not have to use a wrapper in the code to enable logging, 
I'd expect it to be a purely configuration setting.

But even without the LoggingReceive, the unhandled messages are being sent 
to 

  context.system.eventStream.publish(UnhandledMessage(message, sender, 
self))

from the Actor's default "unhandled" body.

But this never seems to be logged? Changing akka.actor.debug.unhandled does 
nothing (maybe this was added in 2.1?) nor does changing 
akka.actor.debug.event-stream.

Given that catching unhandled messages is a critical part of the dev / test 
cycle, I'm really very keen to be able to log these messages.

I've resorted to overriding the unhandled method and using the SLF4J logger 
in there, but what is the "correct" way to do this?

Best regards,
Sam
