        public static java.util.List<java.lang.reflect.Field> findNonNullFields​(@NonNull
                                                                        @NonNull java.lang.Class<?> _class)
        The method uses reflection to find all declared fields of a class that have been marked (via commonly used annotations) as being Non-Null. This method will also look at the class's package level to see if the API for that package is defaulted as Non-Null. ANY annotation that has runtime retention and matches on of the simple annotation names (minus any package) will be considered a match.
        Parameters:
        _class - The class to reflect over
        Returns:
        A list of fields marked as non-null, sorted by their name in alphabetical order.
