The benefit of raising an exception over `return`ing a value will be more evident in the section about Dependencies and Security.

In this example, when the client requests an item by an ID that doesn't exist, raise an exception with a status code of `404`:

            logger.warn("Failed to store crawling information.", e);
        }

        try {
            return crawler.doCrawl(options);
        } finally {
            try {
                crawlingInfoHelper.store(options.sessionId, false);
            } catch (final Exception e) {
                logger.warn("Failed to store crawling information.", e);
            }
