[BUG]fastjson1.2.83升级到2.0.47，原先序列化引用对象的数据，再进行反序列化报错

### 问题描述
*fastjson1.2.83升级到2.0.47，原先序列化引用对象的数据，再进行反序列化报错*

### 环境信息
*请填写以下信息：*

- OS信息： [e.g.：Windows10 ]
- JDK信息： [e.g.：Openjdk 17]
- 版本信息：[e.g.：Fastjson2 2.0.47]

### 重现步骤
1、分别定义1个类（一点要是公共类）

```java
package com.metas.hanger.model.valueobject;

import com.metas.common.dto.BaseDTO;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.EqualsAndHashCode;
import lombok.NoArgsConstructor;

@Data
@EqualsAndHashCode(callSuper = true)
@NoArgsConstructor
@AllArgsConstructor
public class StationNode extends BaseDTO {
private Long id;
private String stationAlias;
private Integer nextStationDistance;
private Long nextStationId;
private StationNode nextStation;

public StationNode(Long id, String stationAlias, Integer nextStationDistance, Long nextStationId) {
this.id = id;
this.stationAlias = stationAlias;
this.nextStationDistance = nextStationDistance;
this.nextStationId = nextStationId;
}
}

```

2、执行测试用例

```java
package com.metas.common.redis;

import com.alibaba.fastjson2.JSON;
import com.alibaba.fastjson2.JSONReader;
import com.metas.hanger.model.valueobject.StationNode;

import java.nio.charset.StandardCharsets;
import java.util.List;

public class T1 {
public static void main(String[] args) {
String s = "[{\"@type\":\"com.metas.hanger.model.valueobject.StationNode\",\"id\":644,\"nextStation\":{\"id\":646,\"nextStation\":{\"id\":648,\"nextStation\":{\"id\":650,\"nextStation\":{\"id\":652,\"nextStation\":{\"id\":654,\"nextStation\":{\"$ref\":\"$[0]\"},\"nextStationDistance\":1,\"nextStationId\":644,\"stationAlias\":\"15_6\"},\"nextStationDistance\":1,\"nextStationId\":654,\"stationAlias\":\"15_5\"},\"nextStationDistance\":1,\"nextStationId\":652,\"stationAlias\":\"15_4\"},\"nextStationDistance\":1,\"nextStationId\":650,\"stationAlias\":\"15_3\"},\"nextStationDistance\":1,\"nextStationId\":648,\"stationAlias\":\"15_2\"},\"nextStationDistance\":1,\"nextStationId\":646,\"stationAlias\":\"15_1\"},{\"$ref\":\"$[0].nextStation\"},{\"$ref\":\"$[0].nextStation.nextStation\"},{\"$ref\":\"$[0].nextStation.nextStation.nextStation\"},{\"$ref\":\"$[0].nextStation.nextStation.nextStation.nextStation\"},{\"$ref\":\"$[0].nextStation.nextStation.nextStation.nextStation.nextStation\"}]";
List stationNode = JSON.parseObject(s.getBytes(StandardCharsets.UTF_8), List.class, JSONReader.Feature.SupportAutoType);
System.out.println(stationNode);
}
}

```
出现异常
```java
Exception in thread "main" java.lang.StackOverflowError
at java.base/java.lang.StringConcatHelper.stringOf(StringConcatHelper.java:453)
at com.metas.hanger.model.valueobject.StationNode.toString(StationNode.java:9)
at java.base/java.lang.StringConcatHelper.stringOf(StringConcatHelper.java:453)
at com.metas.hanger.model.valueobject.StationNode.toString(StationNode.java:9)
at java.base/java.lang.StringConcatHelper.stringOf(StringConcatHelper.java:453)
at com.metas.hanger.model.valueobject.StationNode.toString(StationNode.java:9)
at java.base/java.lang.StringConcatHelper.stringOf(StringConcatHelper.java:453)
```
强转类型后能获得对象数据

Start with the T1 main example and the StationNode class, using the reported fastjson2 2.0.47 setup. Determine whether the StackOverflowError occurs during deserialization or while printing the resulting list through StationNode.toString(). Done means isolating a reproducible library failure from the cyclic-object display behavior and documenting it with a focused regression case.
