org.jboss.netty.handler.codec.http.DefaultHttpResponse cannot be cast to org.jboss.netty.buffer.ChannelBuffer

[이희승 (Trustin Lee)]

I think this is a bug. It should call sendUpstream() instead. Could you change HttpContentDecoder.java:65 from 'ctx.sendDownstream(e);' to 'ctx.sendUpstream(e);' and let me know if it fixes the problem?
