Get if object is created by using reflection?

I have a request that am not able to solve:

Lets suppose I have this class:

    public class DummyPoint {

        private int x;
        private int y;
        private final String id;

        /**
         * @param x
         * @param y
         */
        public DummyPoint(int x, int y) {
            this.x = x;
            this.y = y;
            if(am getting created by reflection??) {
                this.id = UUID.randomUUID().toString();
            }else {
                this.id = "Reflected";
            }
        }
...
    }

In my project that class DummyPoint can be instantiated by:

DummyPoint dp  = new DummyPoint(0,0);
dp.getX();
dp.getY();
dp.getId();

BUT it can be generated by reflection too:

Question:

I would like to know if I can discriminate between an object generated by reflection or not like am trying to do in the constructor.

Is that possible???

What I tried so far:

final DummyPoint dp0 = DummyPoint.class.getConstructor(int.class, int.class).newInstance(0, 0);
final DummyPoint dp1 = new DummyPoint(0, 0);

// ??????
System.out.println(dp0.getId());
System.out.println(dp1.getId());

but both objects are not showing concrete differences in order to make a choice.

thanks
