Issue #123 reproducible on 2.13.0
Code sample:
package test;
import com.fasterxml.jackson.annotation.JsonIdentityInfo;
import com.fasterxml.jackson.annotation.ObjectIdGenerators;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.dataformat.yaml.YAMLFactory;
public class Test {
static class ScratchModel {
public StringHolder foo;
public StringHolder boo;
}
@JsonIdentityInfo(generator = ObjectIdGenerators.None.class)
static class StringHolder {
public String value;
@Override
public String toString() {
return value;
}
}
public void testObjectIdUsingNative() throws Exception
{
final String YAML_CONTENT =
"foo: &foo1\n" +
" value: bar\n" +
"boo: *foo1\n";
System.out.println(YAML_CONTENT);
System.out.println("---");
ObjectMapper om = new ObjectMapper(new YAMLFactory());
ScratchModel result = om.readValue(YAML_CONTENT, ScratchModel.class);
System.out.println(result);
}
public static void main(String[] args) throws Exception {
new Test().testObjectIdUsingNative();
}
}Output:
foo: &foo1
value: bar
boo: *foo1
