> When multiple bundles contain routes with a "cache:" endpoint, if one bundle is stopped, the cache from the other bundle stops working as well.
> Solution : in method doStop of class org.apache.camel.component.cache.CacheManagerFactory, remove the call to cacheManager.shutdown().
> If really useful, a more elaborate reference counting mechanism could be used to stop the CacheManager when the last endpoint is being stopped
> {code}
> Caused by: java.lang.IllegalStateException: The CacheManager has been shut down. It can no longer be used.
