JsonInclude.Include.NON_NULL is ignored for Option.empty in a map

Jackson does not consider Maps POJOs, so this is not expected to work the way described.
But there is SerializationFeature.WRITE_NULL_MAP_VALUES, which should work.

Can you see whether disabling that feature works? (and if not, maybe update problem description).

Hi @cowtowncoder
Thanks for your reply, it works!

It isnt working for me :(
mapper.setDateFormat(new SimpleDateFormat(DATE_FORMAT));
mapper.setSerializationInclusion(Include.NON_EMPTY);
mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);

NON_NULL check will not work, since "Optionals" (Scala's, JDK8's) are not considered null, but rather "absent".
Furthermore, however, handling as Bean/POJO/POSO property differs from inclusion in Map.
So this:

FasterXML/jackson-databind#818

would need to be implemented to support filtering out of Option from Maps, as well as some code changes in Scala map serializers (since they are not java.util.Maps).

If functionality is desired, I would suggest filing a new issue, as NON_NULL will not work so description here is bit off.
