JDK9 features

[Sundararajan Athijegannathan]

Hi,

Thanks for your comments!

Making comments on forthcoming JDK releases is hard :) Whatever I'm
saying now, may not happen - the usual disclaimer applies.

No, we expect that only a subset of ES6 features will be implemented for
Java 9.

1. On loading definitions without changing global namespace: you meant
current global namespace? loadWithNewGlobal creates a new global and
loads definitions into that.

Would that be useful for you? or anything else? Which hack you're
referring to? Please file an enhancement with your requirements.

2. on JSON: Again, will you please provide a simple test case and/or
file an enhancement with requirements?

Thanks,
-Sundar
