Build Identifier: eclipselink-2.3.0.v20110604-r9504

Using the entity:

@Entity
@Table(name="CUSTOMER_TABLE")
public class Customer implements java.io.Serializable
{

    // Instance variables
    private String id;
    private String name;
    public Customer()
    {
    }

    public Customer (String id, String name)
    {
    this.id = id;
    this.name = name;
    }
   @Id
    @Column(name="ID")
    public String getId() {
    return id;
    }
    public void setId(String v) {
    this.id = v;
    }

    @Column(name="NAME")
    public String getName() {
    return name;
    }
    public void setName(String v) {
    this.name = v;
    }
}

Using the client code:


            CriteriaBuilder qbuilder = getEntityManagerFactory().getCriteriaBuilder();
            CriteriaQuery cquery = qbuilder.createQuery();
            Root<Customer> customer = cquery.from(Customer.class);

            System.out.println("Creating select using selection items with the same alias");
            try {
                cquery.select(qbuilder.array(customer.get("id").alias("SAMEALIAS"),
                        customer.get("name").alias("SAMEALIAS")));

                System.out.println("Did not thrown IllegalArgumentException");
                pass = false;
            } catch (IllegalArgumentException iae) {
                System.out.println("received expected IllegalArgumentException");
            } catch (Exception e) {
                pass = false;
                System.out.println("Received unexpected exception", e);
            }

output:


[Creating select using selection items with the same alias
Did not thrown IllegalArgumentException
