@jgchen I haven't tested it, but I think it could look like this

            CancelableStreamObserver<HelloReply> responseObserver = new CancelableStreamObserver<HelloReply>() {
                @Override
                public void onNext(HelloReply reply) {
                    System.out.println("sayHelloServerStream onNext: " + reply.getMessage());
                }

                @Override
                public void onError(Throwable t) {
                    System.out.println("sayHelloServerStream onError: " + t.getMessage());
                }

                @Override
                public void onCompleted() {
                    System.out.println("sayHelloServerStream onCompleted");
                }
            };
            System.out.println("Call sayHelloServerStream");
            greeterService.sayHelloServerStream(buildRequest("triple"), responseObserver);
            responseObserver.cancel(new RuntimeException("cancel"));
