--------------------------------
Summary: camel-netty can't distinguish between Sharable and
Unsharable codecs
Key: CAMEL-5225
URL: https://issues.apache.org/jira/browse/CAMEL-5225
Project: Camel
Issue Type: Bug
Components: camel-netty
Affects Versions: 2.9.2
Environment: ALL
Reporter: edge wang
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:
