Map serialization, null values and @JsonValue

[nnegativ]

Jackson allows skip null values when serializing maps. This doesn't work, when map value is generated by the method annotated with @JsonValue. For example:

@JsonProperty
private Map<String, SomeClass> fields;

and:

class SomeClass {
@JsonValue
public String getValue() { ... }
}

result:

{"id1":"a","id2":null}

Ok. Sounds like a flaw. I'll move this to

https://github.com/FasterXML/jackson-databind

since this is problem with databinding, not streaming API (which this project covers).

Closing, moved to FasterXML/jackson-databind#150
