> I think it's interesting to discuss how many are stuck on java8. [...] But then when 9, 10 and 11 came no one made an effort to upgrade. Why?

A lot of things broke in Java 9, which was short-lived (both it and Java 10 lasted only six months each), and then Java 11 broke many other things (for instance, it removed all of J2EE). As late as last year, I was still seeing changes in libraries to fix issues with Java 9 or later. It's not that no one made an effort to upgrade, it's that it was a lot of effort, and often required upgrading to later versions of libraries, which have their own breaking changes.

In my experience mst of these changes are simple to add to your projects pom or build.gradle. For instance the removal of the jaxb xml runtime is a simple 1 liner to your project:

    runtimeOnly 'org.glassfish.jaxb:jaxb-runtime:2.3.2'
