> CompletionStage documentation says:
> {quote}
> if a stage's computation terminates abruptly with an (unchecked) exception or error, then all dependent stages requiring its completion complete exceptionally as well, with a {@link CompletionException} holding the exception as its cause.
> {quote}
> On the other hand, the CDI spec suggests that if an observer notification fails, the CompletionStage fails with FireAsyncException directly (not wrapped within CompletionException). This creates a conflict as the CDI spec uses the CompletionStage API without fully conforming to its contract.
