@xenoterracide What is the problem, specifically?
you can install 8, but then you can't immediately use it without further work, 11 is still used instead of 8.
@xenoterracide you have to swap your default Java after an install.
/usr/libexec/java_home -V will list them and there are a few ways you can swap (using shell scripting or the jenv tool). https://www.jenv.be/
Some background because I suspect that is what is causing the confusion: java_home is a macOS tool. It selects the java executable to use if you invoke java without specifying the full path to the executable. By default, it always selects the newest one, i.e., the one with the highest version number. Our installers merely install the JDK but do not configure the java_home tool. There is no default place to do so. We‘d need to hack around in .zshrc, .bashrc etc. Besides, users might get confused in the case of updates when suddenly another version becomes active because the update order changed in comparison to the install order.
My recommendation: Set JAVA_HOME explicitly as explained by our README.
closing, this is default macOS behaviour
