Due to PHP Bug #53727, is_subclass_of might return inconsistent results on some PHP versions if \FilmTools\Commons\DensitiesInterface::class can be an interface. If so, you could instead use ReflectionClass::implementsInterface.

            throw new FilmToolsInvalidArgumentException("Class name must implement DensitiesInterface.");
