This statement should not be reachable

Hello,
I'm trying to run the Example1 code, but I get this error:

Exception in thread "main" java.lang.UnsupportedOperationException: Program error. This statement should not be reachable.
at github.footloosejava.go2.Goto._unreachable(Goto.java:173)
at github.footloosejava.go2.Goto.testBasicJump(Goto.java:116)
at github.footloosejava.go2.Goto.(Goto.java:19)

import github.footloosejava.go2.Goto;
import github.footloosejava.go2.transformers.GotoLoader;

public class Example1 extends Goto  implements Runnable {

    public void run() {
        int x = 0;

        _label(0);

        if (x > 0) {
            System.out.println("We jumped back to label 0 before reaching this code!");
            _goto(1);
        }

        x++;
        _goto(0);

        _label(1);
    }

    public static void main(String args[]) throws Exception {
        Runnable demo = (Runnable) GotoLoader.newInstance(Example1.class.getName());
        demo.run();
    }
}
  
  
// This code is in another class (my main application class):
public static void main(String[] args) {
        try {
            Runnable demo = (Runnable) GotoLoader.newInstance(Example1.class.getName());
            demo.run();
        } catch (Exception ex) {
            System.out.println("ERROR: " + ex.getMessage());
        }
    }

I get the same error even if I simply try to run the Example1 class.
