Sorry for a late reply.

Adam gave me a clue so that I can fix this issue finally.  Could you please retry with the
recent snapshot?

> I am not sure if it is a bug or I just misunderstood something.
> I am implementing a protocol and use Demuxing* classes.
> When I return MessageDecoder.OK from my MessageDecoder's decode method, MINA tries repeatedly
calls this method again. If I return MessageDecoder.NEED_DATA everything goes fine.
> So, I would expect completely reversal behaviour.
> I checked CumulativeProtocolDecoder and DemuxingProtocolCodecFactory classes.
> In CumulativeProtocolDecoder.decode it says that doDecode is invoked repeatedly until
it returns false. Fine. But what "false" means here? I would guess that it means that buffer
was completely decoded and no more data is needed. But DemuxingProtocolCodedFactory.doDecode
returns true if decoder returned MessageDecoder.OK and false if decoder returned MessageDecoder.NEED_DATA.
Isn't wrong here?
