Carsten Ziegeler resolved SLING-2468.
-------------------------------------
Resolution: Fixed
Replaced the usage of the key class with ServiceReference
> Use ServiceReference to order adapter factories
> -----------------------------------------------
>
> Key: SLING-2468
> URL: https://issues.apache.org/jira/browse/SLING-2468
> Project: Sling
> Issue Type: Bug
> Components: Extensions
> Affects Versions: Adapter 2.0.12
> Reporter: Carsten Ziegeler
> Assignee: Carsten Ziegeler
> Fix For: Adapter 2.0.14
>
>
> On shutdown of a bundle an NPE might occur during unregistering an adapter
> factory:
> java.lang.NullPointerException
> at
> org.apache.sling.adapter.internal.AdapterFactoryDescriptorKey.<init>(AdapterFactoryDescriptorKey.java:43)
> at
> org.apache.sling.adapter.internal.AdapterManagerImpl.unregisterAdapterFactory(AdapterManagerImpl.java:268)
> at
> The key is currently using bundle id and service id to register and order
> factories. On shutdown of a bundle the bundle might not be available anymore
> from the service reference, therefore the NPE occurs
> It would be better to use the ServiceReference to directly compare and order
> factories. This would not only avoid the NPE but also give a stable ordering
> based on the service ranking of factories.
