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 
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 
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) 
For those cases in which we have an SPIs which isn't really meant to
be third-party pluggable.

 * JEP 384: Records (Second Preview) 
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.

Thanks,
Sanne
