Depends on how you configured hibernate and that depends (to some extend) on the database that is used. So please provide more information.
Also, what is the next id? Have a few gone wrong? is the next 92 or 5000000000000000000000000000008 ;-) or....
The database is Sybase 12.5
The sequence numbers continue from 500000000000000x, incrementing by 1 for each new object.
I did not do any special configuration for hibernate, other than the commands generated by the jbpm-db scripts.
BTW, what happens when the id numbers roll over?
