You can try it by yourself, actually. Start a worker verticle that starts web server with a handler.

public class WorkerVerticle extends AbstractVerticle {

@Override
public void start() {
Router router = Router.router(vertx);

router.route().handler(r -> {
System.out.println(Thread.currentThread().getName());
r.response().end("OK");
});

vertx.createHttpServer().requestHandler(router).listen(8080);
}
}

What will happen is that those requests will be served on the worker thread pool. This is basically the old web container behavior, which kinda kills the entire idea behind Vert.x
