Get all fields values recursively using reflection

I want to go through an object and check for null fields using reflection. The problem starts when there are fields of a complex type/ list of objects. I tried to do it recursivly but got StackOverflowError. Object for scanning example:

    public class MyModel {
    private String name;
    private Integer age;
    private InnerModel innerModel;
    private List<InnerModel> list;
}


public class InnerModel {
    private String description;
}

And let's say I want to check if the description in InnerModel is null. What is the right way to do so with reflection and recursion?
