After working with it for over 20 years, I think it's time has come and gone and that it's not the most efficient way to build enterprise applications anymore. You're lucky that Clojure program still works on the newer JVM because many of the applications I worked on, which were very large, could not be migrated to newer versions of Java. In fact, that experience repeated several times for me. I barely ever worked on anything that used the latest versions of the JVM, every place I worked was always on things like "Java 8" and crap like that. It was infuriating, but the situations were not unique at all.

We built an app in Java 8 a few years ago and are updating it for each LTS version, currently 21. Except for a few issues like the renaming of Javax packages to Jakarta it was pretty smooth so far.
