------------------------------------
Summary: Component deactivation does not cause reference services
to be ungotten
Key: FELIX-6044
URL: https://issues.apache.org/jira/browse/FELIX-6044
Project: Felix
Issue Type: Bug
Components: Declarative Services (SCR)
Affects Versions: scr-2.1.14
Reporter: Thomas Watson
The fix to FELIX-5276 has caused an issue for the default reference scope of
bundle. When a component has a simple @Reference and that component is
deactivated the services that it references will not be ungotten by SCR. This
causes all kinds of issues for use counting of the consumed service.
The issue is that
org.apache.felix.scr.impl.manager.DependencyManager.close(ComponentContextImpl<S>,
EdgeInfo) is calling RefPair.unsetServiceObject now for all RefPair types.
The RefPair types MultiplePrototypeRefPair and SinglePrototypeRefPair were
updated to have unsetServiceObject to also have that service be ungotten. But
the default SingleRefPair type was not. This causes issues when ultimately the
DependencyManagers are deactivated later which then closes the customizer for
the dependency and
org.apache.felix.scr.impl.manager.DependencyManager.AbstractCustomizer.ungetService(RefPair<S,
T>) is called. By this time there will now be a null service and it will not
be ungotten.
