       In Spring Integration, the ApplicationContext plays the central role of a Message Bus, and there are only a
       couple configuration options to be aware of. First, you may want to control the central TaskScheduler instance.
       You can do so by providing a single bean with the name "taskScheduler". This is also defined as a constant:
       <programlisting><![CDATA[ IntegrationContextUtils.TASK_SCHEDULER_BEAN_NAME ]]></programlisting>
-      By default Spring Integration uses the <classname>SimpleTaskScheduler</classname> implementation. That in turn

       it's rather trivial to supply your own configuration. The "taskScheduler" bean is then responsible for managing
