public static List getNullProperties(Object source) {
    final BeanWrapper wrappedSource = new BeanWrapperImpl(source);
    return Stream.of(wrappedSource.getPropertyDescriptors())
        .map(FeatureDescriptor::getName)
        .filter(propertyName -> Objects.isNull(wrappedSource.getPropertyValue(propertyName)))
        .collect(Collectors.toList());
