We no longer really maintain the Hibernate criteria API. The long term plan is to expose the JPA criteria API from Hibernate native apis (Session) and develop extensions on top of that.

That being said, as we are in an "in between time" with that, I am willing to continue to accept and apply patches/PRs fixing bugs in the legacy criteria. But I personally will not be fixing these. I can help direct you if you want to work on this...
