Yes, I know, I just don't understand why it is in the JEP. As far as I know, we
can already do that:
//usr/bin/env javac "$0" && java -cp . Main; exit $?
public final class Main {
public static final void main(String[] args) {
System.out.println("Test");
}
}
Which is crude, for sure, but if `java` can determine that it is a source file,
that would shrink to:
//usr/bin/env java "$0"; exit $?
public final class Main {
public static final void main(String[] args) {
System.out.println("Test");
}
}
