To mitigate this new behavior of the RabbitMQ broker, Spring AMQP has introduced a `retry_count` header starting with version 3.2.
When this header is absent and a server side DLX is in action, the `x-death.count` property is mapped to this header.
When the failed message is re-published manually for retries, the `retry_count` header value has to be incremented manually.
See `MessageProperties.incrementRetryCount()` JavaDocs for more information.
See javadoc:org.springframework.amqp.core.MessageProperties#incrementRetryCount()[Javadoc] for more information.
