My think is there may be much cases to think about. We can just simply do profile in c1.

That's right.  I was just trying to point out why this happens.  C1 was checking final/private on Child1 instead of Parent.  If we wanted to make C1 behave more like the interpreter, then it should do the final/private check on Parent.
