Exception found when use inherit in crd

Bug Report

What did you do?

update java-operator-sdk from 4.3.5 to 4.4.1

What did you expect to see?

CustomResourceUtils.java#L21C9-L21C9 throws Exception

What did you see instead? Under which circumstances?

CRD definition like this:

public abstract class Rb<SPEC, STATUS> extends CustomResource<SPEC, STATUS> implements Namespaced {
}

public class Crd extends Rb<CrdSpec,CrdStatus> {

}

class Crd doesn't implements Namespaced but it's parent Rb does. However CustomResourceUtils.java throws Exception

Environment

Possible Solution

CustomResourceUtils.java should check it's parents.
