AlreadyConnectedException when using netty for client connection

[Y. J. Chun]

Yep. I was calling ctx.sendDownstream(e) except when the state is CONNECTED.
I thought calling sendDownstream() was the default behavior of
SimpleChannelUpstreamHandler.
I modified it to not calling sendDownstream() for all known state and
I see no more exception.
Thanks for the help.
