      Description

      I tried to convert data records currently in a custom format into avro records via a map-only job. To allow for optional record fields I followed the workaround sketched by Doug in AVRO-519 using the generic API.

      When emitting the resulting records a "NoSuchFieldException" is thrown when trying to resolve the union types: Only the methods declared in ReflectData seem to be called, the implementation in GenericData is skipped.
