    Description

      Hadoop RPC fails if MyProtocol extends an interface, which is not a VersionedProtocol even if MyProtocol extends also VersionedProtocol. The reason is that Invocation uses Method.getDeclaringClass(), which returns the interface class rather than the class of MyProtocol.
      This is incompatible with former versions.
