Description

CronComponent invokes setProperties on the CamelCronConfiguration object, which means reflection is used to set the properties:

https://github.com/apache/camel/blob/master/components/camel-cron/src/main/java/org/apache/camel/component/cron/CronComponent.java#L48

It'd be nice if we could avoid this, as otherwise we have to register CamelCronConfiguration for reflection in camel-quarkus.

There's a test case over in the camel-quarkus project using Quartz as the cron scheduler to help prove any fixes:
