HystrixCommand ignoreExceptions not working as expected for Observables Javanica

[smjdowling]

    @HystrixCommand(ignoreExceptions = IllegalArgumentException.class)
    public Observable<User> getUserById(final String id) {
        return Observable.create(new Observable.OnSubscribe<User>() {
                @Override
                public void call(Subscriber<? super User> observer) {
                    try {
                        if (!observer.isUnsubscribed()) {
                            observer.onNext(new User(id, name + id)); //throws IllegalArgumentException
                            observer.onCompleted();
                        }
                    } catch (Exception e) {
                        observer.onError(e);
                    }
                }
            });
    }

When an IllegalArgumentException is thrown then the Observable has HystrixRuntimeException with IllegalArgumentException wrapped. It should have HystrixBadRequestException with IllegalArgumentException wrapped.
