Answer 1

In your @JsonInclude You puted 3 properties. on the other hand you don't add setter and getter to message property.

Duplicated with: Jackson with JSON: Unrecognized field, not marked as ignorable

Answer 2

There is no property with the name message at the class you mentioned. Does something missing from your code? If you're trying to put the message value inside the map so you should remove the specification of message property at the @JsonPropertyOrder .
