Gavin King ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *commented* on HHH-16927 ( https://hibernate.atlassian.net/browse/HHH-16927?atlOrigin=eyJpIjoiMDQ3Nm... ) Re: Some NUMBER column types now get mapped to Boolean/Integer/Long instead of BigDecimal ( https://hibernate.atlassian.net/browse/HHH-16927?atlOrigin=eyJpIjoiMDQ3Nm... ) Right. The change to the major version number 5->6 was made to indicate that this is a version of Hibernate which introduces breaking changes. In principle this should be mentioned in the migration guide, but it might easily have slipped through.
