粘贴入代码，并重命名onStart()，和onStop()能debug了，原来问题原因这么简单

@_'' 终于找到原因了，最笨的办法把继承类MainConfig代码删除后，add uImplemented methods 重构方法，最少不报错了。

我Debug了，代码在jfinal的private void createJFinalConfig(String configClass) { temp = Class.forName(configClass).newInstance();}出错 configClass的代入值 “hqzn.common.config.MainConfig” 正常,再向下跟踪时，没有源码

我把 hqzn.common.config.MainConfig代码都注释了，仍旧报错
