Note that you can use "`" around inline code to have it formatted as code, and you need an empty line to make a new paragraph. As you can see, theres no mention about the shared ForkJoinPool but only a reference to the default asynchronous execution facility which turns out to be the one provided by CompletableFuture#defaultExecutor method, which can be either a common ForkJoinPool or a mysterious ThreadPerTaskExecutor which simply spins up a new thread for each task which sounds like an controversial idea: Luckily, we can supply our Executor instance to the thenApplyAsync method: And finally, we managed to regain full control over our asynchronous processing flow and execute it on a thread pool of our choice. I get that the 2nd argument of thenCompose extends the CompletionStage where thenApply does not. Other times you may want to do asynchronous processing in this Function. . If this CompletableFuture completes exceptionally, then the returned CompletableFuture completes exceptionally with a CompletionException with this exception as cause. It is correct and more concise.
