Ioannis Canellos resolved KARAF-464.
------------------------------------

       Resolution: Duplicate
    Fix Version/s: 2.2.0

Its been a while and I haven't received any feedback on the issue. I couldn't reproduce most
probably because the issue has already been fixed by KARAF-330 so I will mark this one as
duplicate.

> The class org.apache.karaf.jaas.config.impl.OsgiConfiguration contains a java.util.List<JaasRealm>
which is intended to track jaas realms added via blueprint via it's register/unregister pair
using the whiteboard pattern.  This list is not mutated properly during unregister, since
the list is not keyed by name or other id, and the passed in value during remove is a proxy.
 Thus, after doing an "update" on a bundle that contains a jaas configuration, the list grows
by one, but contains a stale service reference.
> When this occurs, a subsequent call to getAppConfigurationEntry() causes a runtime exception,
"org.osgi.service.blueprint.container.ServiceUnavailableException".  No jaas-based authentication
can happen after this.
