Artem Melentev commented on XWIKI-2332:
---------------------------------------

Implementation notes in http://xwiki.markmail.org/message/vs7wbfjv7ipyz2t3
plan:
1st step: HibernateSessionFactory as simple holder for real session factory and configuration
2nd: move hibernate initialization to HibernateSessionFactory.
3rd: remove setters from HibernateSessionFactory and add reconfigure method. (there are many problems with custom mappings)

> XWiki has many hibernate stores. Each store contains own session factory with own connections.
> This cause too many connections to db, long initialization, XWIKI-2328, etc.
> We need to share one session factory among all hibernate stores
