When I compile this program with the modified javac to produce class files that are conformant with the outline in https://cr.openjdk.java.net/~briangoetz/valhalla/sov/04-translation.html:

public inline class Point {

    private int x;
    private int y;


    public Point(int x, int y) {
        this.x = x;
        this.y = y;
    }

    public static void main(String [] args) {
        Point.ref pref = new Point(10, 20);
        System.out.println(pref);
    }
}

I get two class files: Point.class and Point$ref.class.

Running them to jvm I get good behavior.

A slightly modified version of the program above triggers a verification error - don't know why
