camel-akka and response from actor - apache-camel

Question

Dear Akka/Camel Masters!
I have following route:
(netty4:tcp) -> (akka:actor)
I'm using akka-camel module where:
akka:actor is of type UntypedConsumerActor
netty4:tcp is an endpoint defined in getEndopointUri method of akka:actor
netty4:tcp://localhost:8000?textline=true
When I send bytes to tcp socket I receive exception which tells that socket channel is closed:
Caused by: java.nio.channels.ClosedChannelException: null
at io.netty.channel.AbstractChannel$AbstractUnsafe.write(...)(Unknown Source) [netty-all-4.1.4.Final.jar:4.1.4.Final]

What am I doing wrong?

I found a solution. Setting netty endpoint as a one-way solves the problem.
netty4:tcp://localhost:8000?textline=true&sync=false
