Claus Ibsen resolved CAMEL-5225.
--------------------------------

       Resolution: Fixed
    Fix Version/s: 2.9.3

Thanks for reporting.

I have refactored to use the pipeline factory, so we support stateful codecs

> Camel-netty uses general configuration model for referenced encoders/decoders for channel
pipelines, see DefaultServerPipelineFactory. That is, create encoder/decoder objects at configuration
parsing time and store them in a list, then use them when a pipeline is established. However,
this will make encoder/decoder objects shared among different pipelines, that may cause data
conflicts, when the encoder/decoder is not Sharable(has object status/not annotated as @Sharable),
e.g. a LengthFieldBasedFrameDecoder.
> Although we can avoid the problem by totally writing a new serverpipelinefactory for
our apps, several problem still remains, please see detailed description and testcase for
this bug at:
