原来用的1.2.73，升级1.2.76之后造成了生产事故

嵌套多层的json解析提示错误
com.alibaba.fastjson.JSONObject cannot be cast to com.xxxxxx

换回1.2.73后恢复正常，太信任fastjson了，没有进行测试就上线。具体什么原因回头断点看一下，现在忙着解释事故

可以提供更多的堆栈信息么？

new TypeReference<T<List<E>>>(){}

这种格式就会报错

#3761 这就是其中一个问题之一，我们也是升级后遇到了问题

就是二楼说的这个结构，多层转换new TypeReference<T<List>>(){}，获取其中list的时候提示没有这玩意。本来想写个demo的，然后自己在代码中写死原始字符串，转换竟然是成功的，但是从httpclient中获取的字符串转换就是失败了。。玄学了，抽个时间再看看，搭个可以复现的demo
