> java.util.Optional can currently not be used at all when using reflection
> based schemas.
> _org.apache.avro.reflect.ReflectData#getSchema_ will currently produce the
> following type for fields using Optional:
> {"type":"record","name":"Optional","namespace":"java.util","fields":[]}
> The generated schema is completly unusable (it does not contain any data). I
> would like to propose to map Optional fields as if they were not using
> Optional and would be annotated with @Nullable. So resulting in the following
> type:
> ["null","something"]
