Since $knownReaders is declared private, accessing it with static will lead to errors in possible sub-classes; you can either use self, or increase the visibility of $knownReaders to at least protected.

            throw new UnsupportedFileTypeException("Unsupported file type: \"$type\"");
        }

        return static::$knownReaders[$type];
