Description
### 问题描述
*简要描述您碰到的问题。*
Map waveDataMap = JSONB.parseObject(data, Map.class);转换时报错,数组越界。
### 环境信息
*请填写以下信息:*
- OS信息: [e.g.:CentOS 8.4.2105 4Core 3.10GHz 16 GB]
- JDK信息: [e.g.:Openjdk 1.8.0_312]
- 版本信息:[e.g.:Fastjson2 2.x.x]
### 重现步骤
*如何操作可以重现该问题:*
从数据库获取表一条数据,用MAP waveDataMap接受后,通过 byte[] bytes = JSONB.toBytes(waveDataMap);转成byte[],通过socket传送到server端,server端将该byte[]数组反序列化,
Map waveDataMap = JSONB.parseObject(data, Map.class); 发送错误,如果表字段很少可以成功,多了就报错数组越界,SQL语句见附件。

Contributor guide
Research direction
Start by reproducing the JSONB.toBytes and JSONB.parseObject flow described in the issue, using the attached SQL data if available. Compare a map with few fields against the larger database row and capture the complete exception context; done means the server can deserialize the larger payload without ArrayIndexOutOfBoundsException.
