David Bosschaert commented on FELIX-4883:
-----------------------------------------
One other comment, from
https://osgi.org/javadoc/r5/core/org/osgi/framework/ServiceReference.html#getBundle():
bq. This method must return null when the service has been unregistered. This
can be used to determine if the service has been unregistered.
So maybe the current behaviour is correct, although the dto.bundle assignment
should be updated to take this into account.

> Project: Felix
> Issue Type: Bug
> Components: Declarative Services (SCR)
> Environment: Linux, Sling, Adobe CQ, org.apache.felix.scr version
> 1.8.3-R1658944
> Reporter: Rob Ryan
> Assignee: David Bosschaert

> In our test automation we install a large set of bundles after our also large
> 'main' app starts up. This causes significant churn as bundles and components
> are stopped and potentially new versions are started. Unfortunately the coded
> involved is not open source, so I cannot deliver the full data required to
> reproduce the failure described here.
> What I can share is that after all this churn of bundles and components being
> stopped and started the ScrComponentRuntime service starts to fail with a
> NullPointerException in getComponentConfigurationDTOs. This was initially
> noticed as an NPE being reported when visiting the felix console at
> /system/console/components.
> The stack at the point of failure is:
> java.lang.NullPointerException
> at
> org.apache.felix.scr.impl.runtime.ServiceComponentRuntimeImpl.serviceReferenceToDTO(ServiceComponentRuntimeImpl.java:205)
> at
> org.apache.felix.scr.impl.runtime.ServiceComponentRuntimeImpl.satisfiedRefManagersToDTO(ServiceComponentRuntimeImpl.java:169)
> at
> org.apache.felix.scr.impl.runtime.ServiceComponentRuntimeImpl.managerToConfiguration(ServiceComponentRuntimeImpl.java:145)
> at
> org.apache.felix.scr.impl.runtime.ServiceComponentRuntimeImpl.getComponentConfigurationDTOs(ServiceComponentRuntimeImpl.java:119)
> at com.robr.incqtest.test.ScrTest.test(ScrTest.java:37)
> ...
> The NPE occurs because a
> org.apache.felix.framework.ServiceRegistrationImpl.ServiceReferenceImpl being
> processed in
> org.apache.felix.scr.impl.runtime.ServiceComponentRuntimeImpl.serviceReferenceToDTO(org.osgi.framework.ServiceReference<?>)
> line: 205
> has a m_svcObj of null. So even though the bundle is actually available in
> the object the getBundle() method returns null.
> [~cziegeler] [~bosschaert] I can investigate further to ideally narrow this
> down further, but any pointers would be much appreciated.
