[hibernate-dev] Changing group ids from org.hibernate to org.hibernate.{project}

Right, that'd be my hope as well. It'll just more clearly emphasize which
artifacts "belong together" because they are part of the same project.

More fine-grained group ids also help with discoverability of the modules
of one project. E.g. try to find all the backends for Hibernate Search from
this list of >80 artifacts under org.hibernate:
http://mvnrepository.com/artifact/org.hibernate. It looks much more
digestable for OGM: http://mvnrepository.com/artifact/org.hibernate.ogm
which already uses its own group id.

Taking Spring as an example, they also have different group ids for things
like Spring Data, Spring Integration etc. I don't think it harms their
brand.

But yes, it'll be a migration challenge, needing good communication and
education. Personally I think that's acceptable for a major version, esp.
if we happen to do it at the same major (6) for ORM, Search and Validator.
