                In the default configuration (simple MiniGenotypeLoader) NULL is always final and should be used
                to finish processing.

                If the loader is configured to load other objects or stop on other conditions, NULL will also mean
                every condition other than "GenotypeLoaded". In such cases you need MultiParamLoader::getStatus(),
                MultiParamLoader::finished() and other methods to determine the real cause of NULL.
