#PostConstruct: Nested dependency is null - spring

Question

Here, all the dependencies in JobRepository are autowired correctly. But in the init() method,
when jobUtil.findRootCarrier() is called, carrierService inside JobUtil seems to be null and its causing NPE.
#Component
#Transactional(Transactional.TxType.REQUIRES_NEW)
public class JobRepository {
#Autowired
public JobUtil jobUtil;
#Autowired
public JobsInitializer jobsInitializer;
#PostConstruct
public void init() {
Form form = getBatchJobsForm();
.........
}
private synchronized Form getBatchJobsForm() {
Carrier carrier = jobUtil.findRootCarrier();
.........
}
}
#Component
public class JobUtil {
#Autowired
public CarrierService carrierService;
public Carrier findRootCarrier() {
List<Carrier> topLevelCarriers = carrierService.findTopLevelCarriers(); // carrierService is null
}
}
I assumed PostConstruct gets called after all the dependencies including nested ones gets injected. Am I wrong?
Edit
