I also register the implementations for types D.\n\nWhen it comes to de-serialization msgpack picks up the field data as of type D for which it doesn't have any template that could be applied to read the value.\n\nPlease advise on how to solve this - if at all possible.\n","author":{"url":"https://github.com/adicioban","@type":"Person","name":"adicioban"},"datePublished":"2013-08-19T06:06:46.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/2/msgpack-rpc-java/issues/2"}
