The void completion methods don't return new CompletableFuture (no need) but just "return this" to be nice to fluency fans.

aaaaaah, It means that with CompletableFuture c = completableFuture.then(e -> foo(e)); c.isDone() can be true even if foo() has still not finished.

Having a fluent interface is a nice trick but here, the resulting semantics is too weird IMO.
