Not really. J2EE has been around for a while. But it was RADICALLY different and was pretty much horrible. Then it copied many of the AOP aspects of Spring (inject etc) as it evolved. The current standard of Jakarta looks more like Spring than its original form. As such most of the implementations of the standard are much newer. So yes, the standard origins are old but that's not a relevant metric. I said, cross pollination. E.g. just recently the Spring Native example is totally an example of Spring copying a great idea from the Quarkus et al.
