Now it's time to unlink /etc/alternatives with the JVM we want to uninstall.
Usually one has to uninstall each java commands, tools or libraries one by one with the following interactive command:

sudo update-alternatives --remove "java" "/usr/lib/jvm/default-java/jre/bin/java"; |
Doing this task one by one is pretty tedious, we provide a shell script ito facilitate the work.
