I sorry for posting in list, but I need an authoritative answer. I was told by one of the developers of another JVM (Ceylon) language that

CompletableFuture.supplyAsync(() -> "Hejjo Worjd from Java") .thenApply(s -> s.replaceAll("j","l")) .thenAccept(System.out::println);

would eventual fail to print if run enough times. Is this true?

Your snippet looks correct to me. You could use jstress [1] to try to catch the alleged bug. And in case you succeed, you could then produce a sscce as Martin suggested. -------------------------------------------------------------------------------- [1] http://openjdk.java.net/projects/code-tools/jcstress/
