What is the first: the first call to #orTimeout() or the call with the lowest timeout? CompletableFuture cf = ... cf.onTimeout(10L, TimeUnit.MINUTES); // 1. call cf.onTimeout(10L, TimeUnit.SECONDS); // 2. call cf.onTimeout(10L, TimeUnit.HOURS); // 3. call As far as I understand the implementation, the second call wins. What I miss from the JavaDocs is following: It is allowed to call the #onTimeout()-methods multiple times. But it does not mean that subsequent calls would override already defined timeout and that the lowest timeout wins.
