Hibernate generates negative id values when using a sequence

Question

I have a class with the following definition:

@Id
@SequenceGenerator(name = \"SEQ_ACE_WORKERS_QUEUE_STATS_ID\", sequenceName = \"SEQ_ACE_WORKERS_QUEUE_STATS_         


        

Answer 1

Setting hibernate.id.new_generator_mappings to false in my persistence.xml was just the first part of the solution to my problem:

To completely solve the problem I added the allocationSize to 1 in the @SequenceGenerator (which I was omitting).
