[jira] [Resolved] (FELIX-4883)
ServiceComponentRuntime.getComponentConfigurationDTOs NullPointerException
[ https://issues.apache.org/jira/browse/FELIX-4883?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
David Bosschaert resolved FELIX-4883.
-------------------------------------
Resolution: Fixed
I mistakenly thought that the attached zip contained a testcase. [~rryan@adobe.com], I have put a defensive check for nulls on the line that you indicated: http://svn.apache.org/viewvc?view=revision&revision=1681073
As creating a ServiceReferenceDTO for a null ServiceReference does not make any sense, I'm having it return null. I have also updated the calling side to be able to deal with the null return value: http://svn.apache.org/viewvc?view=revision&revision=1681097
Please reopen if this doesn't fix it for you.

> Environment: Linux, Sling, Adobe CQ, org.apache.felix.scr version 1.8.3-R1658944
> Reporter: Rob Ryan

> 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.
