   1. `sofa application` 容器启动时 调用`SofaModuleBeanFactoryPostProcessor `执行 
`postProcessBeanFactory `方法 会把当前 容器中`BeanFactoryPostProcessor ` 
`BeanPostProcessor `类型的 `BeanDefinition `都注册存储到  
`PROCESSORS_OF_ROOT_APPLICATION_CONTEXT  `中，此时 
`ReferenceAnnotationBeanPostProcessor` 已经被从当前容器中移除 `BeanDefinition `实例也同时销毁 
，但是`DubboInfraBeanRegisterPostProcessor` 类型的 `BeanDefinition ` 被加入了

   2. 在 sofa 子模块容器启动时 创建子容器以后 会从父容器中获取`PROCESSORS_OF_ROOT_APPLICATION_CONTEXT 
`类，获取 到 `DubboInfraBeanRegisterPostProcessor` 注册到子容器中，在执行到 
beanFactoryPostProcessor 方法时 从容器中获取 `ReferenceAnnotationBeanPostProcessor` 
bean的时候  子容器中 并没有 `ReferenceAnnotationBeanPostProcessor` 
对应的实例和相关的`BeanDefinition ` 父容器中也没有 所以会抛出异常。
