Method Reconciler#reconcile is not triggered when resource is deleted.

Reproduziere das Problem mit dem bereitgestellten MyResourceReconciler und der ControllerConfiguration und verfolge anschließend den Ereignisverarbeitungspfad bis zu Reconciler#reconcile für Löschereignisse. Erledigt ist die Aufgabe, wenn eine Löschung eine Reconciliation mit context.isPrimaryResourceDeleted() true auslöst, während das Verhalten bei Erstellung und Aktualisierung unverändert bleibt; füge Tests zur Abdeckung hinzu oder aktualisiere sie, falls die relevanten Tests zur Ereignisverarbeitung gefunden werden.

Bug Report

I wanted to create metric exporter for certain resource type.
For this I implemented Reconciler with triggerReconcilerOnAllEvents enabled (introducerd in JOSDK 5.2) to receive all events (create, update and delete).

Method Reconciler#reconcile is not triggered when resource is deleted.

What did you do?

@ControllerConfiguration(triggerReconcilerOnAllEvents = true, generationAwareEventProcessing = false)
public class MyResourceReconciler implements Reconciler<MyResource>{

    private static final Logger LOG = Logger.getLogger(MyResourceReconciler.class);

    @Override
    public UpdateControl<MyResource> reconcile(MyResource resource, Context<MyResource> context) throws Exception {
	   LOG.infof("Resource %s/%s event", resource.getMetadata().getNamespace(), resource.getMetadata().getName());
        if(context.isPrimaryResourceDeleted()){
            LOG.infof("deleted");
            return UpdateControl.noUpdate();
        }
        LOG.infof("created/updated");
        return UpdateControl.noUpdate();
    }

}

What did you expect to see?

When I create, update and delete resource I expected to see in logs:

INFO  [com.test.MyResourceReconciler] (ReconcilerExecutor-myresourcereconciler-92) Resource mynamespace/myresource event
INFO  [com.test.MyResourceReconciler] (ReconcilerExecutor-myresourcereconciler-92) created/updated
INFO  [com.test.MyResourceReconciler] (ReconcilerExecutor-myresourcereconciler-93) Resource mynamespace/myresource event
INFO  [com.test.MyResourceReconciler] (ReconcilerExecutor-myresourcereconciler-93) created/updated
INFO  [com.test.MyResourceReconciler] (ReconcilerExecutor-myresourcereconciler-93) Resource mynamespace/myresource event
INFO  [com.test.MyResourceReconciler] (ReconcilerExecutor-myresourcereconciler-93) deleted

What did you see instead? Under which circumstances?

When I create, update and delete resource I see in logs:

INFO  [com.test.MyResourceReconciler] (ReconcilerExecutor-myresourcereconciler-92) Resource mynamespace/myresource event
INFO  [com.test.MyResourceReconciler] (ReconcilerExecutor-myresourcereconciler-92) created/updated
INFO  [com.test.MyResourceReconciler] (ReconcilerExecutor-myresourcereconciler-93) Resource mynamespace/myresource event
INFO  [com.test.MyResourceReconciler] (ReconcilerExecutor-myresourcereconciler-93) created/updated

Additional context

• resources does not have finalizers
• adding defaultFilters = false to ControllerConfiguration did not helped
