Apply this BeanPostProcessor to the given new bean instance after any bean
initialization callbacks (like InitializingBean's
afterPropertiesSet
or a custom init-method). |

In case of a FactoryBean, this callback will be invoked for both the FactoryBean
instance and the objects created by the FactoryBean (as of Spring 2.0). The
post-processor can decide whether to apply to either the FactoryBean or created
objects or both through corresponding bean instanceof FactoryBean checks.
This callback will also be invoked after a short-circuiting triggered by a
InstantiationAwareBeanPostProcessor.postProcessBeforeInstantiation(java.lang.Class<?>, java.lang.String) method,
in contrast to all other BeanPostProcessor callbacks.
