It has been raised: http://issues.apache.org/jira/browse/CHAIN-12 "they subclass ContextBase and inherit the "implements Serializable" contract, but they cannot in fact be serialized because they wrap container objects (request, response,context) that are not serializable" ...and we don't have a solution for it - so no fix.
