Answer 1

你是说有多个同类的包，版本不一样吗？没有啊
并且是ClassReloadingBeanFactory.createBeanInstance（）调用.ClassReloadingBeanFactory.resolveBeanClass（）的时候说没有resolveBeanClass（）这个方法
看源码好像是resolveBeanClass这个方法的调用和声明是不一样的，调用的时候用的两个参数，声明的时候用的是三个参数。

This feature is experimental, and should never be used in production systems. 这个功能是实验性的，不要用到生产系统中去。（struts2 Guide)
