The quartz2 documentation (http://camel.apache.org/quartz2.html) suggests to define the bean for customizing the component.
But if the bean is defined with id="quartz" then org.apache.camel.impl.DefaultFactoryFinder is not resolving it to the component created by Spring. So if a route is defined with "quartz2://..." then it ends up creating a new instance of the QuartzComponent.
However, if you define the bean with id="quartz2" then it DefaultFactoryFinder is able to resolve to the instance created by Spring.
So, either the documentation needs to be updated or the component resolution code needs to be fixed.
