CBOR loses Map entries with specific long Map key values (32-bit boundary) #269
Description
The issue only appears to occur with large keys of opposite sign. See the below reproducer.
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.dataformat.cbor.CBORFactory;
import java.util.HashMap;
import java.util.Map;
public class CBORLongMapReproducer {
private static final ObjectMapper json = new ObjectMapper();
private static final ObjectMapper cbor = new ObjectMapper(new CBORFactory());
public static void main(String[] args) throws Exception {
Map<Long, String> map = new HashMap<>();
map.put(4294967296L, "hello");
map.put(-4294967296L, "world");
TestData data = new TestData();
data.setMap(map);
Map<Long, String> resultCbor = cbor.readValue(cbor.writeValueAsBytes(data), TestData.class).getMap();
Map<Long, String> resultJson = json.readValue(json.writeValueAsBytes(data), TestData.class).getMap();
System.out.println("JSON size: " + resultJson.size());
System.out.println("CBOR size: " + resultCbor.size());
}
public static class TestData {
private Map<Long, String> map;
public void setMap(Map<Long, String> map) {
this.map = map;
}
public Map<Long, String> getMap() {
return map;
}
}
}This program produces the following output:
JSON size: 2
CBOR size: 1
