You can maybe just define a Spring <bean> and have a stop method being
invoked from it. There is a attribute you can set in the <bean> to
refer to a start|stop method.
And then have maybe a "depends-on" -> Camel is needed. To help Spring
with the ordering.
<bean id="myStatBean" depends-on="myCamel">
<camelContext id="myCamel" ...>
