[jira] Updated: (ARIES-420) Leverage Whiteboard pattern for interceptors

     [ https://issues.apache.org/jira/browse/ARIES-420?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Joe Bohn updated ARIES-420:
---------------------------

        Summary: Leverage Whiteboard pattern for interceptors  (was: Register interceptors as services and add a service reference to applicable bean)
    Description: Our current interceptor implementation is dependent upon registering a pojo for the interceptor with the component metadata.   When constructing a bean (or service in the case of the newly introduced quiesce service interceptor) we retrieve the interceptor pojo(s) and use it in construction of the proxy.  There are potential lifecycle issues with this if the bundle which introduced the interceptor is later removed from the system.  A whiteboard pattern would improve lifecycle management such that the bundle dependencies can be better managed.
