I am using Play for Java. As of 2.7.x, I have noticed that Play is still using JPA 2.1 when 2.2 is out for a while now. I have not been able to find any mention in the roadmap regarding this.
I have also noted that the JPA 2.2 module on maven is a beta version. Is this the reason why Play has not upgraded to JPA 2.2? Also, how could a specification be on beta? Shouldn’t the APIs be standardised before releasing the standard?
