Your link is about a completely separate feature, called the AOT code cache (targeted for JDK28, not released yet). The post is about the AOT cache, which forms the foundation for this feature, but is separate and already available since JDK24. The JEP for the feature the post is about is https://openjdk.org/jeps/483

I wonder if this should trigger a warning (or even an error) at application startup whenever the CPU architectures differ.

IMHO, that would be much better than running into crashes and having to figure out the cause yourself.

Yeah, there are some strange expectations going into this.
