watch 命令使用 json 格式时，容易出现 java.lang.StackOverflowError: null

原因是 fastjson2 序列化时死循环了：

```
2025-12-05 16:31:18 [detailAsyncActivityThread-1518] ERROR c.taobao.arthas.core.view.ObjectView -ObjectView draw error, object class: class java.util.ArrayList
java.lang.StackOverflowError: null
```

```

```

Start with the watch command's JSON output path and the ObjectView component named in the error. Reproduce the StackOverflowError with the reported watch cases, then inspect the fastjson2 writer calls in the stack trace to identify the recursive object relationship. Done means watch JSON output completes without the serialization overflow, with coverage for the failure case.
