I'd really like to get this working with ORM 5.1, since that is what we 
want to upgrade WildFly 11 to use.  The best idea that I have for that 
would be via a Javassist 3.18.3-GA that would contain a backport of the 
changes (which means that we would need to build 3.18.3-GA with the JDK9 
EA javac.)

I'm not sure if we have enough time to do this (Javassist) backport but 
if that is the best way to get ORM 5.1 working with JDK9, we could do 
the work, when we find the time.  This would likely be after Java9

As discussed on IRC, not yet, as Java 9 is still changing.  There is a 
nightly build WildFly build that produces a zip [1].
