Yes. Hibernate 5. The JPA EG decided to not address discriminator based tenancy in JPA 2.1 so fortunately/unfortunately we are on our own to define how this works.
In terms of when... I certainly hope this year. Though that may not be Final. EE 7 (JPA 2.1) probably won't be final in that time. More help gets it done faster, if you want to volunteer some help...
