YAML anchors don't seem to work with @JsonCreator

[ryegleason]

Java code:

@JsonIdentityInfo(generator=ObjectIdGenerators.IntSequenceGenerator.class)
class Student {
	private String name;
	private Integer age;

	@JsonCreator
        public Student(@JsonProperty("age") int age, @JsonProperty(value = "name") String name){
		this.name = name;
		this.age = age;
	}

        public String toString(){
            return "Student [ name: "+name+", age: "+ age+ " ]";
    }
}

public static void main(String args[]){
        try {
            YAMLMapper mapper = new YAMLMapper(new YAMLFactory());

            Student student = mapper.readValue(new File("student_yaml.yml"), Student.class);

	        System.out.println(student);
        }
        catch (Exception e) {
	        e.printStackTrace();
        }
    }

student_yaml.yml:

---
&1 name: "billy"
age: 5

Runtime Error:

com.fasterxml.jackson.databind.JsonMappingException: No Object Id found for an instance of Student, to assign to property '@id'

So for this, when attempting to use the YAML anchor notation, it doesn't seem to be recognized. Everything works fine when I make Student stop using JsonCreator (and make the fields public, of course), or change student_yaml.yml to

---
'@id': 1
name: "billy"
age: 5
