> 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.
