-------------------------------------------------------------

camel-netty have been improved for Camel 2.10.

And if you use decoders/encoders that cannot be shared with multiple consumers, then you need to enlist 2 in the registry etc.
This is *not* a bug, but how its designed. You as the end user must configure the endpoints/components correctly.

I have added your test to the source and it passes on trunk.

> 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:
