Part of this effort of integrating Hibernate 5, will be passing the various TCKs (from standalone JPA 2.1 TCK to EE TCKs).  Once we have some TCK runs with Hibernate 5, we will have a better idea of how much work is remaining on the Hibernate ORM 5.x side.

Since we are short on time, I wanted to pass the TCK tests before (merging Hibernate 5.0 into WildFly 10) but am flexible on that if the schedule could be flexible also.

You could create a JPA branch and get it far enough along to run the JPA tck tests on it, and in the meantime everyone could fork that branch as needed for their development branches. Once we get promising looking results the branch can be converted into one or more PRs.

I agree that we need the TCK picture before we merge. If there are a few minor failures thats fine, we can merge while those are being sorted out. The important thing would be to catch any major issues so that they can be addressed in time. 

Does 5 have significant TCK impacting changes? I heard there was work on a new query engine, but don’t remember if that was for 5 or the future.
