Over time, most apps have begun to provide their own jvm. The others use various mechanisms such as setting JVM_HOME or editing a shell script to allow user to choose a suitable JVM. I always let the distro pick the "default" Java (e.g., openJDK), and install Oracle Java when one of my apps needs something that doesn't work properly with the distro package. It is an annoyance that apps use different, poorly documented, mechanisms to control which JRE is used. https://fedoraproject.org/wiki/Java says multiple Java versions should coexist in Fedora (use alternatives to select the one you want to be active) -- George N.
