msgpack-idl generate java codes which msgpack-java cannot serialize.

[everpeace]

• about Tuple:
  msgpack-java doesn't have serializer( org.msgpack.template.*Template class) for Tuple.java, so instances of generated Tuple class cannot be serialized. It would be better that TupleN.java is in msgpack-java.
• about HashMap, ArrayList:
  Although msgpack-idl generates java codes using HashMap, ArrayList class for Map,List type, msgpack-java does have only have templates for interfaces of Map,List. It would be better that msgpack-idl generate java code using Map,List interfaces.

Sorry for not reporting concrete error messages. I would report concrete errors next week.
