Nashorn Roadmap & Rhino migration question

[Hannes Wallnoefer]

Hi Paul,

Regarding your question on EcmaScript 6: Our plan is to add ES6 features 
incrementally. First on our list is block scoping with let and const 
which should be in the 8u40 release. We're also reviewing a patch of 
contributed Array, Object, String, Math, and Number functions added in 
ES6. Beyond that plans are still moving, but ES6 features will continue 
to show up in update and major releases.

Complete ES6 is quite a big undertaking so it's definitely beyond JDK8 
and at least the initial JDK9 release. Whether ES6 will be backported to 
a JDK 8 update release at some point is too early to tell I guess.

Regards,
Hannes
