[BUG] parseObject异常抛出文案不友好

[oday-xiexin]

问题描述

简要描述您碰到的问题。

环境信息

请填写以下信息：

• OS信息： [e.g.：windows10]
• JDK信息： [e.g.：Openjdk 1.8.0_312]
• 版本信息：[e.g.：Fastjson2 2.0.6]

重现步骤

如何操作可以重现该问题：

1. 使用 xxx.xxx 方法
2. 输入 ... 数据
3. 出现 ... 错误

//可在此输入示例代码

期待的正确结果

对您期望发生的结果进行清晰简洁的描述。
相比1.2.84 转换异常抛出的文案比较友好，如java.lang.Integer cannot be cast to com.alibaba.fastjson.JSONObject，但fastjson2 只会抛出com.alibaba.fastjson.JSONException: illegal input， offset 1, char 2

相关日志输出

请复制并粘贴任何相关的日志输出。
