---------------------------------------
Summary: 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.
