NPE when component exposed as a service with servicefactory = true
------------------------------------------------------------------
Key: FELIX-3288
URL: https://issues.apache.org/jira/browse/FELIX-3288
Project: Felix
Issue Type: Bug
Components: Declarative Services (SCR)
Affects Versions: scr-1.0.2
Reporter: Jarek Gawor
I have a component that is exposed as a service and is also configured with
servicefactory = true. I see the following NPE when shutting the framework:
java.lang.NullPointerException

Since the component is configured with servicefactory = true,
ServiceFactoryComponentManager is used to manage the object.
ServiceFactoryComponentManager overrides the createComponent() method from
ImmediateComponentManager. ServiceFactoryComponentManager also intended (I
think) to override the corresponding deleteComponent() method from
ImmediateComponentManager. However, the signature of the deleteComponent() in
ImmediateComponentManager has changed a bit so the override doesn't work
anymore. So that's what I think is causing the problem in this case.
