Hello spring-team :wave:
As JUnit Jupiter comes with many new features through annotations (such as @TestInstance or @Order), it makes sens that they be ignored by the key created by ImportsContextCustomizer.
This is a small patch, but one can wonder if the key should not consider only org.springframework.* annotations or supply an extension point for custom user-defined annotations to be ignored when creating the context caching key (part).
Let me know if you need more contexts.
Best regards !

I think it makes sense to ignore org.junit imports. We already do the same for Spock. Unfortunately I don't think we can just limit ourselves to org.springframework.* since users might have their own annotations. I do think an extension point is a good idea. I've raised https://github.com/spring-projects/spring-boot/issues/28564 for that.
