[MNG-8376] Exit with a nicer error message when running on JDK < 17

[gnodet]

Needs to be tested on windows, or maybe just add an IT ?

Why not, sounds reasonable...via toolchains?

We assume thet user have awk ....
What do you think to create a simple class like:

public class CheckJavaVersion {
    public static void main(String[] args) {
        if (Double.parseDouble(System.getProperty("java.vm.specification.version")) < 17.0) {
            System.exit(2);
        }
    }
}

compile with target 8, put in bin directory

it will be easy to execute and check statu code of execution

I just changed the script to simply rely on java to verify that the argument can be used.
