Rob Ryan commented on FELIX-4883:
---------------------------------
The changes don't look like they address the situation where the
ServiceReferenceImpl.getBundle() may return null.
I will try to make time to abstract the proprietary code into a publicly
disclosable form that can demonstrate what is happening.

> Key: FELIX-4883
> URL: https://issues.apache.org/jira/browse/FELIX-4883
> 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
> Priority: Minor
> Fix For: scr-2.0.0

> Attachments: scrtest.zip

> 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.
