* forces the predicted type of a FactoryBean, effectively preventing retrieval of the
* bean from calls to #getBeansOfType(FactoryBean.class). The implementation of
* {@link AbstractBeanFactory#isFactoryBean(String, RootBeanDefinition)} now ensures
* that not only the predicted bean type is considered, but also the original bean
* definition's beanClass.
