Both the licensing issues and the upgrade cost are largely myths. Licensing is only an issue if you want to keep using the free Oracle JDK, but there is seriously no need to. JDK upgrades were never drag and drop. When we upgraded Java 6 to Java 8 we had just about the same amount of issues we had when upgrading Java 8 to 11. Some libraries had to be updated. Bloated Application servers like Tomcat and Glassfish (let alone beasts of legend like WebLogic) needed an entirely new major version to cope with that. The misconception that Java 11 is an especially rough upgrade comes from exaggerated worries about modules and perhaps the faster rate of change. 8 years have passed between Java 6 to Java 8, but only 4 years have passed between Java 8 to Java 11.
