Kulla JEP update -- feedback requested

[Robert Field]

Before the Kulla JEP can move forward we need an up-to-date JEP.   I 
have done the first draft of this update:

        https://bugs.openjdk.java.net/browse/JDK-8043364

Please give me any feedback on problems with this (yes, please tell me 
about nits too).
I'd like to know what you see as missing.

In particular, I currently have nothing in the "Risks and Assumptions" 
section.

Information on testing and tab-completion, etc is minimal.  Andrei? Jan?

Thanks,
Robert
