 Version 2.1.3 added `pause()` and `resume()` methods to listener containers.
 Previously, you could pause a consumer within a `ConsumerAwareMessageListener` and resume it by listening for a `ListenerContainerIdleEvent`, which provides access to the `Consumer` object.
-While you could pause a consumer in an idle container byi using an event listener, in some cases, this was not thread-safe, since there is no guarantee that the event listener is invoked on the consumer thread.
+While you could pause a consumer in an idle container by using an event listener, in some cases, this was not thread-safe, since there is no guarantee that the event listener is invoked on the consumer thread.
 To safely pause and resume consumers, you should use the `pause` and `resume` methods on the listener containers.
 A `pause()` takes effect just before the next `poll()`; a `resume()` takes effect just after the current `poll()` returns.
 When a container is paused, it continues to `poll()` the consumer, avoiding a rebalance if group management is being used, but it does not retrieve any records.

 Starting with version 2.5, you can now configure the deserializer, via properties, to invoke a method to determine the target type.
 If present, this will override any of the other techniques discussed above.

 Set these properties to the method name - a fully qualified class name followed by the method name, separated by a period `.`.
 The method must be declared as `public static`, have one of two signatures `(byte[] data, Headers headers)` or `(byte[] data)` and return a Jackson `JavaType`.
