how to help with ES6 features

[Hannes Wallnöfer]

Hi Paulo,

Excellent! I’d be happy to help you and sponsor this work. 

Do you think your existing code would work in Nashorn, or would it be a reimplementation based on that prototype? In any case, a link to the code would be nice to get an idea of what’s involved.

Also, before contributing to OpenJDK you have to sign and send in the committer agreement as described in http://openjdk.java.net/contribute/ . If you aren’t a committer already we can help you with this.

Hannes
