[hibernate-dev] 6.0 Alpha1 prep

As I am preparing the Alpha1 release a few topics of discussion have come up... Previously (last year's f2f) we had decided to unify the artifact naming conventions; specifically for ORM this meant renaming the groupId from `org.hibernate` to `org.hibernate.orm` as part of 6.0. I wanted to see if everyone still agrees with this. There are a few artifacts we need to decide how to handle: - `hibernate-entitymanager` and `hibernate-java8` have been part of `hibernate-core` since 5.2 (I thought moving `hibernate-entitymanager` happened way earlier, but seems like not). Should we drop these? They have been defined as relocations for quite some time now). - `hibernate-ehcache` defines support for using Ehcache 2 as a second-level cache, which is a version the Ehcache team does not even support anymore and have not for quite a few years. Ehcache 3 is a JCache compliant version and the way that the Ehcache team prefer to handle the integration (in fact they wrote most of `hibernate-jcache`). IMO this should be removed as well. Thoughts? - `hibernate-infinispan` - support for using Infinispan as a Hibernate L2C has been moved to the Infinispan project. Again, IMO this module should go away. Thoughts? Andrea, Chris.. anything you can think of that I missed?
