oh, that's not good. I remember we refactored Rolling Update API in like kubectl in https://github.com/fabric8io/kubernetes-client/pull/2272

@dixingxing0 : Does it work when you change rolling update of replicationController like this(L149-151):

                // Update the RC via rolling update with inline builder
                client.replicationControllers().inNamespace("thisisatest").withName("nginx-controller")
                        .rolling().updateImage("nginx:stable-alpine");
