Break in fabric8 kubernetes client mock server - fabric8

Question

We were using fabric8 kubernetes client 5.3.x for watcher and it worked fine. Recently when we moved to 5.11.2 there were many changes observed and eventually the JUnit Tests started failing.
We use io.fabric8.kubernetes.client.server.mock.KubernetesServer
Earlier we were using ContainerStatus .withNewReady which now seem to be removed.
And then we added the following annotation
#Rule
public KubernetesServer myMockServer = new KubernetesServer(false, true);
After this, we are getting the following logs stating unsupported label requirement while the application code is sending this label.

Is there something more should be done? Tests are in ERROR state and not Failed.
Sample JUnit program
public void testAddNewPodWatchEvent()
{
//given
doReturn(myClientMock).when(myTestObj).getClient();
doReturn(myWatcherSpy).when(myTestObj).createEventHandler();
String PATH =
"/api/v1/namespaces/test/pods?labelSelector=app.kubernetes.io%2Fname%20in%20%28apps%29&timeoutSeconds=0&watch=true";
Map<String, String> mockLabelMap = new HashMap<>();
mockLabelMap.put("foo", "testlabel");
mockLabelMap.put("app.kubernetes.io/name", "apps");
Pod accPod = createAppsPod(mockLabelMap, true);
myMockServer.expect()
.get()
.withPath(PATH)
.andUpgradeToWebSocket()
.open()
.waitFor(100)
.andEmit(new WatchEvent(accPod, "ADDED"))
.done()
.once();
//when
myTestObj.activate(mockProps);
sleepForWatchToBeInvoked();
//then
verify(myWatcherSpy, atLeastOnce()).eventReceived(Action.ADDED, accPod);
