Sprite Builder should display some error when user sets the physics shape to circle and tries to set the corner values of dynamic physics body to 0.

[Shahidwerplay]

1. Launch Application.
2. Create a new project.
3. Drag and drop a CCPhysics Node.
4. Drop to physics bodies under it, enable their physics, make one of them static and other dynamic.
5. Change the physics shape of both physics bodies to circle and sets their corner values =0.
6. Publish the project, build and run it on XCode.

--Observe: Xcode terminates with error: Body's mass and moment must be positive to simulate.

--Result: Sprite Builder should display some error when user sets the physics shape to circle and tries to set the corner values of dynamic physics body to 0.
