Java 9
Is anyone working on support for running Spark on Java 9? Is this in a
roadmap anywhere?
Cheers,

Hi,
Let me fill you in on the Quality Outreach.
I send out email every 2-3 weeks depending on contents of the builds,
example attached.
I try to highlight significant changes in the builds, allowing you to
decide if you might want
to test with a particular build. We don't expect you to test every
build, it's entirely up to you.
If you would like us to list your project(s) on the Quality Outreach
wiki [1] , can you provide a
contact name , mailing list , the current status of you testing against
JDK 8 & JDK 9, and a
CI if possible ?
Rgds, Rory

tl;dr:
The critical internal APIs proposed to remain accessible in JDK 9 are:
sun.misc.{Signal,SignalHandler}
sun.misc.Unsafe (The functionality of many of the methods in this class is
now available via variable handles (JEP 193).)
sun.reflect.Reflection::getCallerClass(int) (The functionality of this
method may be provided in a standard form via JEP 259.)
sun.reflect.ReflectionFactory.newConstructorForSerialization

Excuse me,
more detail of JDK 9 can be found here .
http://openjdk.java.net/projects/jdk9/
The changes mentioned below were tracked in http://openjdk.java.net/jeps/260
If you want something digested, technical sessions in recent JavaOne
would be quite helpful.
There is a Quality Outreach program. Welcome to join and feedback.

Well and the module system!

If I'm not wrong, they got fid of *sun.misc.Unsafe *in Java 9.
This class is till used by several libraries & frameworks.

Yes, I agree but it may be worthwhile starting to look at this. I was just
trying a build and it trips over some of the now defunct/inaccessible
sun.misc classes.
I was just interested in hearing if anyone has already gone through this to
save me duplicating effort.
Cheers,

I don't think anyone's tried it. I think we'd first have to agree to drop
Java 7 support before that could be seriously considered. The 8-9
difference is a bit more of a breaking change.
