URL: https://github.com/apache/camel/pull/2581
CAMEL-12905: The trigger that starts the SpringCamelContext and that collect to routes to the camel context, needs to be a expected ContextRefreshedEvent that has been emitted by the ApplicationContext that instantiated the SpringCamelContext instance.

> Key: CAMEL-12905
> URL: https://issues.apache.org/jira/browse/CAMEL-12905
> Project: Camel
> Issue Type: Bug
> Reporter: omar alles
> Priority: Major
>
> In a Spring Cloud environment some components might create a child application context that spring cloud mantains. Such is the case for Feign and Ribbon Clients.
> See 7.2 - https://cloud.spring.io/spring-cloud-netflix/multi/multi_spring-cloud-feign.html
> "A central concept in Spring Cloud’s Feign support is that of the named client. Each feign client is part of an ensemble of components that work together to contact a remote server on demand, and the ensemble has a name that you give it as an application developer using the @FeignClient annotation. Spring Cloud creates a new ensemble as an ApplicationContext on demand for each named client using FeignClientsConfiguration."
> This child application contexts are going to be an ApplicationEvent source for the SpringCamelContext and RoutesCollector component who are defined as ApplicationEvent listeners in a parent context.
> SpringCamelContext is intended to be started after a ContextRefreshedEvent.
> RoutesCollector intends to add routes to the camel context after a ContextRefreshedEvent.
> When there are child application contexts (ContextRefreshedEvent emitters) we end up having some inconsistencies in the camel context lifecycle.
