      Description

      Whenever refreshing a bundle that creates a camel context via blueprint, the warning below appears in the logs:

      16:11:44.779 WARN [Blueprint Event Dispatcher: 1] Error occurred while stopping lifecycle strategies. This exception will be ignored.

      It appears that the Blueprint container is being destroyed before the camel context, but the camel context tries to access the bundle when stopping. And since the blueprint container is already destroyed, that fails.

      Reverting this change fixes the warnings: https://issues.apache.org/jira/browse/CAMEL-14332

      Note: Everything appears to work fine when the bundle is started. Still, the warnings are concerning

      To reproduce:

      1. Create a bundle with this blueprint.xml
      <?xml version="1.0" encoding="UTF-8"?>
      <blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0">
        <camelContext xmlns="http://camel.apache.org/schema/blueprint" id="camelContext"/>
      </blueprint>
      
      1. Install in Karaf
      2. Refresh the bundle
