Kind is null in for GenericKubernetesResource informer `ResourceEventHandler

[csviri]

Describe the bug

When I create an informer that uses GenericKubernetesResource the kind of the existing resources is null, sample:

var informer = client.genericKubernetesResources("v1","ConfigMap").inAnyNamespace().runnableInformer(0);
        informer.addEventHandler(new ResourceEventHandler<GenericKubernetesResource>() {
            @Override
            public void onAdd(GenericKubernetesResource configMap) {
                System.out.println("config map kind "+configMap.getKind());
            }

            @Override
            public void onUpdate(GenericKubernetesResource configMap, GenericKubernetesResource t1) {
            }

            @Override
            public void onDelete(GenericKubernetesResource configMap, boolean b) {
            }
        });
        informer.start();

It is already null in cache.
It is strange that, if I create a new ConfigMap with the client, it gets propagated properly.

@csviri the issue seems to be that off of a list operation the api server populates the list kind, but not the individual item kinds, so this would affect any generic list operation not just what the informer is using.

When you receive an event, that's just a single resource and does have the kind populated.

We can probably workaround this by setting the kind ourselves.

so this would affect any generic list operation not just what the informer is using.

This doesn't affect standard resources because the kind is hard-coded in the model.

We can probably workaround this by setting the kind ourselves.

I assume this is the only way to go.
