Roman Kaufmann commented on KAFKA-9234:
---------------------------------------

I would also support the comment from [~CatchDepthHeightLight] :
Spring-Framework 7 & Spring-Boot 4 replaced their own Null-Annotations with the 
new “standard” JSpecify ones [Null Safety in Spring applications with JSpecify 
and 
NullAway|https://spring.io/blog/2025/03/10/null-safety-in-spring-apps-with-jspecify-and-null-away]
 * release date of new Spring Major Version November 2025
 * compile-time null safety with NullAway [GitHub - uber/NullAway: A tool to 
help eliminate NullPointerExceptions (NPEs) in your Java code with low 
build-time overhead|https://github.com/uber/NullAway]
 * This is also used by Spring internally as can be read in the linked blog 
above

>From a developer perspective this would definitely help to avoid a bunch of 
>NPEs in daily business. Are there any updates regarding the dev mailing list 
>discussions or plans to get similar support in an upcoming release?

> Consider using @Nullable and @Nonnull annotations

> Java7 was dropped some time ago, and we might want to consider usein Java8 
> `@Nullable` and `@Nonnull` annotations for all public facing APIs instead of 
> documenting it in JavaDocs only.
> This tickets should be broken down in a series of smaller PRs to keep the 
> scope of each PR contained, allowing for more effective reviews.
