   private int INACTIVE_IND;
   @Column(nullable=true)
   private String GEN_ID;
 
public class BillingConsolidation {
   
   @Id

public class TestingService {


   public static void main(String args[]){
SessionFactory factory =
   new Configuration().configure("hibernate.cfg.xml").buildSessionFactory();
Billing_Cons_Producer_Assoc obj = new Billing_Cons_Producer_Assoc();
Session session = factory.openSession();

Query query = session.createQuery("select * from Billing_Cons_Producer_Assoc c inner join "
+ "Billing_Consolidation b on B.Billing_Cons_Id=C.Billing_Cons_Id ");
       ArrayList a = (ArrayList) query.list();
       System.out.println(a.size());
factory.close();

That says that you should have many BillingConsolidations, but you are only mapping it to a single BillingConsolidation.
