Guillaume Nodet created FELIX-3820:
--------------------------------------
Summary: Possible NPE in ConfigAdmin after shutting down when
accessed by bad behaving bundles
Key: FELIX-3820
URL: https://issues.apache.org/jira/browse/FELIX-3820
Project: Felix
Issue Type: Bug
Components: Configuration Admin
Reporter: Guillaume Nodet
Priority: Minor
When a bundle accesses the ConfigAdmin service while or after it has been
stopped, NPE can occur because the internal
ConfigurationAdminImpl#configurationManager field has been nulled.
While this is a minor issue, it would be better to throw a nicer exception
indicating the COnfigAdmin service has been stopped.
This is mostly for bad behaving bundles that do not react to the service being
unregistered though, so it's really a minor issue
