NUMBER_SERVICES_NOT_MATCH_AFTER_UPDATE_CWOBJ6413=CWOBJ6413W: After updating the {0} OSGi service from the old service ranking {1} to the new service ranking {2}, the number of service instances is changed from {3} to {4}.
Explanation
One possible explanation is that the new service might be referencing a bean that is using a different scope.
User response
Check the plug-in service bundle to make sure the scope of the bean referenced by the service does not change between different versions.
