> When an interface is not declared (which is the case here because we would
> like to export the class :
> org.apache.activemq.camel.component.ActiveMQComponent), then Spring uses
> CGLIB. What we see here is that CGLIB does not find spring core classes
> (which are deployed as bundle in SMX4 - Spring )
