+ * Magento 2 autoloader calls \Magento\Framework\Code\Generator
+ * which is supposed to generate missing classes, e.g. Factories, Proxies, Interceptors.
+ * For some reason, it throws \RuntimeException in \Magento\Framework\Code\Generator::tryToLoadSourceClass
+ * when it finds out that the class for which a factory supposed to exist is also missing.
+ * It's the case which we have in \Enqueue\Magento2\Model\EnqueueManager where, for example,
+ * for missing \Enqueue\Stomp\StompConnectionFactory Magento tries to generate a factory
+ * based on Enqueue\Stomp\StompConnection, but this class is also missing and this leads to the exception.
+ *
+ * To prevent such behavior from Magento, we could handle this exception.
