Netty codecs have "protected" method preventing easy reuse outside pipeline

[Christian Migowski]

Hello,

why don't you implement your logic (en/decode) into a public method
(with the signature as you like it) and call this method in the
"official" encode/decode methods? Seems much more reasonable to me
than requesting an API change for your usecase.

regards,
christian
