For values returned from an @EventListener method, ApplicationListenerMethodAdapter detects arrays/collections and publishes every single element as an event. However, for its CompletionStage check (as applied to a CompletableFuture), it always publishes the given Object as-is. It should delegate to the publishEvents methods with its arrays/collections check as well.
