AlreadyConnectedException when using netty for client connection

[Y. J. Chun]

By the way,
in the SimpleChannelUpstreamHandler source code, ChannelStateEvent is
sent downstream by default. Is this correct?
why sendDownstream() not sendUpstream()?

>From line number 23 of  SimpleChannelUpstreamHandler.java of netty-3.1.2.GA
            case INTEREST_OPS:
                channelInterestChanged(ctx, evt);
                break;
            default:
                ctx.sendDownstream(e);
            }
        } else if (e instanceof ExceptionEvent) {
