I'm sorry for not posting the complete example.  The claim was, given
enough trials, this program will eventually fail to print due to a race
condition.

import java.util.concurrent.*;
public class HelloWorld {

    public static void main(String[] args) {
        CompletableFuture.supplyAsync(() -> "Hejjo Worjd from Java")
                         .thenApply(s -> s.replaceAll("j","l"))
                         .thenAccept(System.out::println);
    }
}

I doubt this claim, but I'm in no position to counter it.  Thanks for help
you can provide.
