加载多个apatch文件报错

测试在Android 5.0-6.0下加载多个aptch文件, 运行被修复代码crash
同样过程在Android 4.0上并不会有问题.
**这个库是不是不支持在art runtime下进行多次修复.**
## 错误日志:

Reproduce the multiple-apatch loading case on Android 5.0–6.0 and compare it with Android 4.0, starting from MainActivity.java:45 and the IllegalAccessError in the report. Read the affected patch-loading path and determine whether repeated fixes are supported under ART; done means the cause and supported behavior are documented or the crash is fixed and verified.
