Some components trigger BeanPostProcessorChecker warning "is not eligible for getting processed by all BeanPostProcessors"

Using Spring Framwork 4.1.4 + Spring Integration 4.1.2 triggers the warning from BeanPostProcessorChecker about early configuration of bean and their inability to be processed by BeanPostProcessors.

This happens even with a very trivial app consisting only of a inbound stdin adapter, a channel and a poller: add <int:annotation-config/> to the context XML and you'll get the warning. Same thing happens using AnnotationConfigApplicationContext and the @EnableIntegration annotation (since both it and the xml directive just defers to IntegrationRegistrar).

I've created a simple project on GitHub to reproduce the problem.
