> ChangeStateTask.getSortKey will internally call getResource().getEntityId(), whereas getResource() might return null.
> I tracked this down on my system to be a concurrency issue where the ResourceState of the task is being updated from UNINSTALL to INSTALLED by an update event. Since the state is now INSTALLED getResource() will return null since it is checking for resource in state UNINSTALL oder INSTALL.
