Java RMI Factory callback medfører at programmet ikke afslutter

Registry registry = LocateRegistry.getRegistry("localhost",1099);
                IClient remoteObject = (IClient)registry.lookup("Client");
//               
                IReceiveDataFactory factory = new ReceiveDataFactoryImpl(); // <-- ERROR

Når jeg opretter en ny ReceiveDataFactoryImpl gør at programmet ikek afslutter, men venter på noget?

Implementering ser sådan ud:
public class ReceiveDataFactoryImpl extends UnicastRemoteObject implements IReceiveDataFactory{

    /**
    *
    */
    private static final long serialVersionUID = 1L;

    public ReceiveDataFactoryImpl() throws RemoteException {
        super();
    }


    public IReceiveData getReceiveData() throws RemoteException {
        return new ReceiveDataImpl();
    }
}

Nogen der kan fortælle mig hvorfor jeg oplever dette? Jeg synes ikke udmiddelbart det giver nogen mening.
