When we tried upgrading from hibernate-annotations 3.1beta8 to 3.2.1.ga the assignment to an id field for at least one class started behaving very strangely. The mapping did not change and specifies that the id field be generated from a sequence. But my sequence is at around 5,000,000,000 and the records are being created with ids around 250,000,000,000

After rolling back to 3.1 the problem goes away. Is there a problem with my mapping that only surfaces in the newer version? Any suggestions on how to figure out what is going on - I added logging and do see the larger number in the object prior to commit.

@Entity
@Table(name = "shipments")
@SequenceGenerator(name="SHIPMENT_SEQ", sequenceName="shipment_id_sequence")
public class Shipments {

@Id
@Column(name = "shipment_id")
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "SHIPMENT_SEQ")
public long getShipmentId() {
return shipmentId;
}

That appears like a bug to me. You may have to use:

That is the line:
@SequenceGenerator(name="SHIPMENT_SEQ", sequenceName="shipment_id_sequence")
---- will look like---
@SequenceGenerator(name="SHIPMENT_SEQ", sequenceName="shipment_id_sequence", allocationSize = 1, initialValue= 1 )

Note that allocationSize = 1 is more important....

Thank you so much, it worked!
