Furthermore, you can package a JDK or JRE with the application, such that the application uses the packaged JDK/JRE, and ignores any that may be installed on the OS. JDK/JRE's are open source, and binaries are available from AdoptOpenJDK, Red Hat, Azul Zulu, and others. "Maintenance" might be to simply swap out one JDK with a newer one and then make sure the app still works -- which it should. But there ARE some ancient things in Java that are being deprecated. Or moved out to separate libraries not bundled into the JRE. I would also point out that with Docker you could package every possible dependency into the container. The container is now portable and has no dependencies outside of what is packaged in the container. To the user, they don't care what technology or Rube-Goldberg contraptions exist within the container. Also see AppImage.
