system object of interface type inside another system object

    Hi, I have the following example:

    public class ParentSystemObj extends SystemObjectImpl {
    public MyInterface anotherSystemObj;
        public MyInterface getAnotherSystemObj() {
        return anotherSystemObj;
    public void setAnotherSystemObj(MyInterface anotherSystemObj) {
        this.anotherSystemObj= anotherSystemObj;

    This is the SUT:


    The type of my internal system object (anotherSystemObj) is an interface. When I try to run a test the anotherSystemObj does not go through init by the framework eventhough I provide an actual class (not interface) in the SUT. Is there any way to get this to work without providing an actual/abstract class in the member type in the code itself inside the parent system object class?

    BTW, if I try to the same but not a system object inside another one, i.e. in the test layer I have:

    MyInterface anotherSystemObj;
    anotherSystemObj= (MyInterface) system.getSystemObject("anotherSystemObj");

    This works, but I want the system object to be inside another one, not by itself

    AFAIK it should work but there are too few details to tell.
    in the past we used a base class that derived from SystemObjectImpl and not as an implementor of SystemObject - can you please prepare a simple project that reproduces it?
