title: Does Vertx 3 support CompletableFuture?
body: <p>I want to develop my application promise style using vertx and CompletableFuture fits really for this purpose but JVM uses fork/join on the background for CompletableFuture and this may break Vertx Thread Safety.</p>
  
  <p>Do you have any idea or have used this feature on your project?</p>
