Re: [hibernate-dev] Strange sequence effect with ORM 5
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.

Hi all,
after upgrading Hibernate Search to Hibernate ORM 5.0.0.Final we
noticed a small change in behaviour in sequences.
In a single test we persist two entities of differnent types, Country
and Address, and both types have the id mapped as follows:
@Id
@GeneratedValue
Long id;
Previously, when running on H2, the IDs assigned to these two entities
would be respectively 1 and 1.
When upgrading ORM from 5.0.0.CR3 to 5.0.0.Final, the assigned ids are
now 1 and 2.
Are sequences now being shared by default across unrelated entities?
Is this the new intended default?
Thanks,
Sanne
