Provide a code like:

public class WeakBoolean {
	private Boolean myBool;

	public WeakBoolean() {
		myBool = true;
	}

	public void inverse() {
		myBool = !myBool;
	}

	public void xor(boolean b) {
		myBool ^= b;
	}
}

Make sure "Type may be weakened" is On. It shows the warning "Type may be weakened to Object" for myBool.
On applying this quick fix the code becomes not compilable.
