This is because pathSegmentService is null. The component containing the
service definition is not yet activated yet and the call of this service is
done in the activate method of
org.nuxeo.cm.core.service.CaseManagementComponent. If the component is loaded
after the activate, it is setting pathSegmentService to null.
The fix can consist of: adding a "require" tag on CaseManagementComponent or
lasy loading the service.
