-----------------------------------------------------------------
I end up with depending on {{javax:json:javax.json-api:1.1}} and in its
{{{}javax.json.JsonValue{}}}, there is;
{{public interface JsonValue {}}
/**
The empty JSON object.
@since 1.1
*/
{{static final JsonObject EMPTY_JSON_OBJECT =
Json.createObjectBuilder().build();}}
And that is somehow redirected back to the Johnzon implementation of
{{JsonObjectBuilderImpl}}

> JsonValue.EMPTY_JSON_OBJECT is set to null, because the initialization of
