Please see the migration guide and/or blogs :) Yes, we changed the default mapping for how id generators are mapped as discussed extensively on the mail list last month or earlier this month. Essentially we changed the default for `hibernate.id.new_generator_mappings` from false to true for 5.0. For H2, the old mapping would have been an IDENTITY column. The "new" mapping is the SequenceStyleGenerator.

Well you can do that. Thats just not historically how Hibernate worked. Set `prefer_sequence_per_entity` to true On Fri, Aug 21, 2015 at 10:26 AM Sanne Grinovero <sanne(a)hibernate.org&gt; wrote: > Ok, thanks and sorry I missed this :) > I was aware that it would switch to sequences rather than identity, > but I missed that there would be a single Sequence shared among > types...
