> After adding the excludeNullProperties param to JSON-type result, when the object to serialize is a map and the value of an entry is null, keeps writing fields with null values like {property_name: null}
> If you change JSONWriter (line 356): Object value = entry.getValue(); if (!excludeNullProperties || value != null) { ..... } everything is ok.
