ApplicationListenerDetector should ignore non-managed bean instances [SPR-14879]

[spring-projects-issues]

Juergen Hoeller opened SPR-14879 and commented

As indicated by the Spring Integration team, our ApplicationListenerDetector issues a warning not only for non-singleton inner beans but also for bean instances which are simply not managed by the container at all, i.e. not backed by a bean definition but rather created through the AutowireCapableBeanFactory interface and externally managed or manually registered as a singleton instance via registerSingleton. Let's revise this to only log a warning for actual non-singleton inner bean definitions.
