[jira] [Created] (FELIX-3288) NPE when component exposed as a
service with servicefactory = true
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
at org.apache.felix.scr.impl.manager.ImmediateComponentManager.disposeImplementationObject(ImmediateComponentManager.java:252)
at org.apache.felix.scr.impl.manager.ImmediateComponentManager.deleteComponent(ImmediateComponentManager.java:135)
at org.apache.felix.scr.impl.manager.AbstractComponentManager$Satisfied.deactivate(AbstractComponentManager.java:1075)
at org.apache.felix.scr.impl.manager.AbstractComponentManager.disposeInternal(AbstractComponentManager.java:357)
at org.apache.felix.scr.impl.manager.AbstractComponentManager.dispose(AbstractComponentManager.java:196)
at org.apache.felix.scr.impl.config.ConfiguredComponentHolder.disposeComponents(ConfiguredComponentHolder.java:299)
at org.apache.felix.scr.impl.BundleComponentActivator.dispose(BundleComponentActivator.java:319)
at org.apache.felix.scr.impl.Activator.disposeComponents(Activator.java:340)
at org.apache.felix.scr.impl.Activator.bundleChanged(Activator.java:207)
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.

The patch looks correct to me. Is there any chance of compiling with java 5 and using @Override to catch stuff like this?

> 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.
