Java 使用FasterXML解析带别名的yml文件

我有一个包含多个对象的yaml文件和一个使用yaml v1.2规范中的锚/别名（&/*）的列表：

key1:
  subkey: &myalias
    - attr1: valueX
      attr2: valueY
      attr3: valueZ
    - attr1: another_valueX
      attr2: another_valueY
      attr3: another_valueZ
key2:
  subkey: *myalias

我有以下Java类：

package com.acme.model;

import lombok.Data;
import java.io.Serializable;

@Data
public class FileObject implements Serializable {

    private KeyObject key1;
    private KeyObject key2;

    public FileObject() {}

}

---

package com.acme.model;

import lombok.Data;
import java.io.Serializable;

@Data
public class KeyObject implements Serializable {

    private SubkeyList subkey;

    public KeyObject() {}

}

---

package com.acme.model;

import com.fasterxml.jackson.annotation.JsonIdentityInfo;
import com.fasterxml.jackson.annotation.ObjectIdGenerators;
import lombok.Data;
import java.io.Serializable;
import java.util.ArrayList;

@Data
@JsonIdentityInfo(generator = ObjectIdGenerators.PropertyGenerator.class, property = "subkeyId")
public class SubkeyList extends ArrayList<SubkeyObject> implements Serializable {

    private String subkeyId;

    public SubkeyList() {}

}

---

package com.acme.model;

import lombok.Data;
import java.io.Serializable;

@Data
public class SubkeyObject implements Serializable {

    private String attr1;

    private String attr2;

    private String attr3;

    public SubkeyObject() {}

}

但出现了以下例外情况：

com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize instance of `com.acme.model.SubkeyList<com.acme.model.SubkeyObject>` out of VALUE_STRING token
 at [Source: (BufferedInputStream); line: 10, column: 11] (through reference chain: com.acme.model.FileObject["key2"]->com.acme.model.KeyObject["subkey"])

com.fasterxml.jackson.databind.exc.mismatchdinputException:无法反序列化'com.acme.model.SubkeyList'的实例值不足\u字符串标记
在[Source:（BufferedInputStream）；行：10，列：11]（通过引用链：com.acme.model.FileObject[“key2”]->com.acme.model.KeyObject[“subkey”]）

我还没有找到将别名和锚点用于列表或地图的文档，仅用于对象

com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize instance of `com.acme.model.SubkeyList<com.acme.model.SubkeyObject>` out of VALUE_STRING token
 at [Source: (BufferedInputStream); line: 10, column: 11] (through reference chain: com.acme.model.FileObject["key2"]->com.acme.model.KeyObject["subkey"])
