I am getting this warning when deploying after upgrading from RC6 to RC7

Hibernate does not support SequenceGenerator.initialValue()

I use sequence generator but I don't set the initialvalue. Don't know why this warning shows up.

for example, this is my sequence generator definition:

@Entity
@SequenceGenerator(name = "sg", sequenceName = "seq_billingdetail")
public class BillingDetail implements Serializable {
...
...

please advise
