Document that Java 25 is the minimum supported version where AOT cache can be used

[helpermethod]

While the documentation correctly mentions that the AOT Cache is available since Java 24, the snippet which demonstrates the creation of the AOT Cache only works with Java 25, as the -XX:AOTCacheOutput is not part of Java 24.

$ java -XX:AOTCacheOutput=app.aot -Dspring.context.exit=onRefresh -jar my-app.jar

It would be great if there would be another snippet which demonstrates the AOT Cache creation using Java 24.

I'm not sure that we should do this. Java 24 is a non-LTS release and, therefore, is no longer supported. I'd rather update the docs to clarify that Java 25 is the minimum supported version where AOT cache can be used. In the meantime, the earlier iteration of the docs that should work with Java 24 is available should anyone need it.

I also believe we should not document flags that no longer are the ones that are promoted going forward.

That makes sense, thanks for the quick answer.

Hi, I'd love to contribute a fix for this. Would a PR that adds a Java 24-specific snippet alongside the existing one be the right approach, or would you prefer just updating the version note? Happy to wait for guidance before opening a PR.

@Rajith-14 After discussing #50471 (comment) we decided that we don't want to add a Java 24 example to the docs. We'd rather add a note that you need to be using Java 25 for AOT caches. If you want to submit a PR in that direction, it would be most welcome!
