When debugging the following code, the hotspot VM reports incorrect values for the variables l, f, and d.

public class Bug5 {
    public static void main(String args[]) {
        long l = 22;
        float f = 6.66f;
        double d = 7.77;

        System.out.println("l="+l +", f="+f + ", d="+d);
    }
}

JDB under hotspot:
