sunflower: Steps to reproduce:
- Copy the code to the editor:
-----------------------------------------------------------
class A{
    public function show() {  // <-- Set a breakpoint
            println("A");
    }
}

class B extends A{
    override function show() {   // <-- Set a breakpoint
            println("B");
    }
}

var a = A{};
a.show();

var b = B{};
b.show();
-----------------------------------------------------------

- Set breakpoints to the show() function in the A and B classes
- Debug the project

- Go to the Variables window
- Add the following expression  to the watch:  name + "1"
The ClassCastException  pops up
