[hibernate-dev] Hibernate and JSR-107 (was Re: 5.1 tentative release date)

Hi all, I am interested in helping finalising that JSR-107 H2LC. I will start looking into the code Alex has on his branch on github and take it from there. I may need to ping hibernate devs directly at one point since I do not have a very good knowledge of Hibernate currently.
