Auto-configured ConcurrentPulsarListenerContainerFactory and PulsarConsumerFactory cannot be injected into injection points with specific generic type information

[jonas-grgt]

It is not possible to inject a specifically typed PulsarConsumerFactory nor ConcurrentPulsarListenerContainerFactory where the former is blocking creating custom typed consumers.
@onobc you probably have an opinion on this.

Thanks for the contribution @jonasgeiregat .

These 2 beans were the only ones typed as Object so this brings things into a consistent state. I am not sure why we had them typed as such, but will see if @philwebb can refresh my memory. Either way, they should be consistent w/ the other bean types.

My only suggestion is to add/adjust test for these 2 cases.

Disclaimer, I have a non-binding vote in Spring Boot project so will need to wait for one of the Boot team members to follow on w/ their review.

Thanks

I'm not sure it was intentional. Despite many years of Java experience I still struggle with generics. Usually my default rule is wildcards on parameters and concrete types on return values so I probably just followed that.

@jonasgeiregat It would be useful to see a sample or test that shows the failure with the current arrangement.

I have added a test that should prove the failure. Simply changing <?> back to will trigger an injection error.
