Macros dont working with POJOs (CLOSED)

Question

i don't know what or if i'm doing it wrong, but the conversion from json to my POJOs just don't work. I'm with the dependencies updated. When i called the method "readJSONFromURL" my return always is the object with yours attributes with value NULL. All the libs are up to date.

My Objects:

public class ListHall {

private List<Hall> Hall;

public void setHall(List<Hall> hall) {
    this.Hall = hall;
}

public List<Hall> getHall() {
    if (Hall == null) {
        this.Hall = new ArrayList<Hall>();
    }
    return Hall;
}

}

public class Hall {

private String id;
private String name;
private Integer count;

//getter and setters here

}

My DataMappers:

data_mapper ListHall:ListHallMapper
data_mapper Hall:HallMapper

My method conversor:

public ListHall mapHall() throws IOException {
    ListHallMapper returnListHallMapper = new ListHallMapper();
    HallMapper hallMapper = new HallMapper();
    DataMapper.createContext(Arrays.asList(returnListHallMapper,
            hallMapper),
            (DataMapper mapper) -> {
                mapper.setReadKeyConversions(Arrays.asList(DataMapper.CONVERSION_CAMEL_TO_SNAKE));
            });
    return returnListHallMapper.readJSONFromURL("http://192.168.0.16:7080/integration/hall", ListHall.class,"/ListHall");
}

My output JSON:

{"ListHall":{"Hall":[{"id":"0","name":"Salão 1","count":"10"},{"id":"f6a495c1-be5e-4476-a362-5d42e572bfae","name":"Salão 3","count":"0"}]}}

My result:




My LIB:

What i'm doing it wrong?
