-------------------------------

             Summary: CacheManager should only be shutdown when last endpoint 
is stopped
                 Key: CAMEL-7174
                 URL: https://issues.apache.org/jira/browse/CAMEL-7174
             Project: Camel
          Issue Type: Bug
          Components: camel-cache
    Affects Versions: 2.8.5
         Environment: ServiceMix 4.4.2
            Reporter: metatech
            Priority: Minor


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.
