Inner bean behind BeanFactoryPostProcessor should be able to receive application events [SPR-14783]

[spring-projects-issues]

Pavel Mukhataev opened SPR-14783 and commented

Spring bean doesn't get subscribed to application events if inner bean is used as a property for bean that implements BeanFactoryPostProcessor.

BeanFactoryPostProcessor bean itself get subscribed to application events, while it's inner beans are not.

Addressed through early registration of our ApplicationListenerDetector ahead of BeanFactoryPostProcessor initialization, subsequently re-registered after BeanPostProcessor initialization in order to pick up proxies etc.
