Call restController in asynchronous method with vaadin

I have some problem with firing RestController when I want to fire it from a Thread. I'm trying to send a request to RestController from my thread but I don't get any response from the controller when my restTemplate is executing destination URL. RestController isn't even executed. It is working as expected only if I'm sending a request from ui.access->rest.sendRequest(), but then my application must wait for the end of the request anyway.

I'm working with Vaadin 14. I created a thread with a run method like this:

CompletableFuture<Long> nonBlocking = CompletableFuture.supplyAsync(() -> restTemp.getForObject("http://localhost:4240/Servis/api/address",
    Long.class));
nonBlocking.thenAccept(s -> {
    if (s != null) {
      ui.access(() -> Notification.open("long is not null"));
    } else {
      ui.access(() -> Notification.open("long is null"));
    }
});
nonBlocking.get();

But my code from the rest controller is still not executed.
