------------------------------------------
Summary: NPE in StoredWiringResolver if BundleEvent.UNRESOLVED
handled before BundleEvent.RESOLVED event
Key: KARAF-5211
URL: https://issues.apache.org/jira/browse/KARAF-5211
Project: Karaf
Issue Type: Bug
Components: karaf-feature
Affects Versions: 4.1.1, 4.2.0
Reporter: Christopher Lockard
When upgrading from karaf-4.0.7 to karaf-4.1.1 we are seeing several NPE
exceptions in the log related to Activator handling BundleEvent.UNRESOLVED
before BundleEvent.RESOLVED events are recieved. This results in a NPE in
StoredWiringResolver.delete(...)
