问题原因

出现这个异常的原因是很明确的，在更新字节码时，增加/删除了field。可能有下面的原因：

JDK的bug，尽量用最新的JDK版本，特别是JDK8

比如： redefine热更新报错 #969 (comment)

其它的java agent修改了字节码，增加了 field。

比如jacoco，这个代码测试覆盖率工具，它会在类里增加一个static field来记录执行信息。

其它的java agent修改了字节码，但是在retransform时，生成同样的字节码

比如skywalking：无法trace 和watch加载skywalking7 的jar中的类方法 #1141

在执行arthas redefine/retransform命令时，用户自己想替换的字节码有修改

可能是用户本地的JDK版本和线上的JDK版本不一致导致的

可能是用户自己修改了源码

解决方法

暂时关闭 skywalking
