Many thanks Rory! All, there's plenty of great features here which are relevant to Hibernate; I hope you're having a look. Unfortunately we're still aiming at backwards compatibility with Java8 for our main projects, but I hope some of us will want to start experimenting with these. Some suggestions: * JEP 371: Hidden Classes <http://openjdk.java.net/jeps/371> Some of the classes we generate might be a good candidate to be "hidden"? Although I have to warn I haven't fully understood this JEP, it will require some exploration. * JEP 378: Text Blocks <http://openjdk.java.net/jeps/378> Expressing SQL queries is the canonical example of this JEP; clearly it's going to be useful for HQL as well. I suppose it will "just work", but it would be good to verify this, see how it looks, and if there's improvements we can do to our API / documentation / examples. * JEP 360: Sealed Classes (Preview) <http://openjdk.java.net/jeps/360> For those cases in which we have an SPIs which isn't really meant to be third-party pluggable. * JEP 384: Records (Second Preview) <https://openjdk.java.net/jeps/384> Since they are immutable, they aren't a good fit for entities; but they seem like a great way to represent a scalar query result, as sets of parameters for queries, and there's possibly some desire to use them mappeddd as embeddable types.
