        Optional<List<LoginConfiguration>> loginModuleEntries) {
    // Generally the entries will be null only in situations like unit/integration tests.
    if (loginModuleEntries.isPresent()) {
        List<LoginConfiguration> sorted = new ArrayList<>(loginModuleEntries.get());
        sorted.sort(new AnnotationAwareOrderComparator());
