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.
