Aim :- Check whether the contain() & intersects() return the correct value , when circle is place with the substracted portion of the ShapeSubtract .

I have a ShapeSubtract where i am placing rectangle to a & ellipse to b. I am adding a circle in the substrated place of the shape. Even i have added mouselistener to the ShapeSubtract & the circle, so that i can check for mouseEntered & mouseExited events. When i mouse the mouse pointer on the ShapeSubtract the mouseEntered events are triggered , in the same way when i mouse the mouse on the substrated shape mouse exit event is triggered which are correct. When i click either on the ShapeSubtract or on the circle. I am checking for contains() & intersect() value .

I am getting wrong value for contains() when i move the circle with in the ShapeSubtract portion.

I have attached the testcase
