 The `CachingConnectionFactory` now unconditionally disables auto recovery in the underlying RabbitMQ `ConnectionFactory`, even if a pre-configured instance is provided in a constructor.
 While steps have been taken to make Spring AMQP compatible with auto recovery, certain corner cases have arisen where issues remain.
 Spring AMQP has had its own recovery mechanism since 1.0.0 and doesn't need to use the recovery provided by the client.
-While it is still possible to enable the feature (using `cachingConnectionFactory.getRabbitConnectionFactory().setAutomaticRecoveryEnabled()`) after the `CachingConnectionFactory` is constructed, it is **strongly recommended that you not do so**.
+While it is still possible to enable the feature (using `cachingConnectionFactory.getRabbitConnectionFactory()` `.setAutomaticRecoveryEnabled()`) after the `CachingConnectionFactory` is constructed, it is **strongly recommended that you not do so**.
 Use a separate RabbitMQ `ConnectionFactory` if you need auto recovery connections when using the client factory directly (rather than via Spring AMQP components).
