Currently BlackFlagActor will assign a value to CONFIG.SYSTEM.CLASS_DOCUMENTS only if CONFIG.SYSTEM.BACKGROUND_DOCUMENTS is empty. This is not guaranteed, so subsequent checks of CLASS_DOCUMENTS are at risk of throwing unhandled exceptions if no actor has called its own #loadForeignDocuments method.
