Subject [jira] Created: (KARAF-464) JAAS service configuration tracker does not unregister services or respond to service updates
Date Tue, 15 Feb 2011 20:25:57 GMT
JAAS service configuration tracker does not unregister services or respond to service updates
---------------------------------------------------------------------------------------------

                 Key: KARAF-464
                 URL: https://issues.apache.org/jira/browse/KARAF-464
             Project: Karaf
          Issue Type: Bug
          Components: runtime
            Reporter: Kurt Westerfeld


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.
