A decoder could output ByteBuffer again and let it decoded later in
the next ProtocolCodecFilter.  For now, all our filter implementations
doesn't work correctly when they are added more than once to one
filter chain.

We discussed about this issue one day, and decided to generate a
dynamic session attribute key which includes the filter's hash code.

So... you will be able to add more than one protocol codec filter in
2.0.  You can't for now with 1.x unfortunately.
