While Groovy/Jruby etc have seen constant updates, and engines like V8 and SpiderMonkey make continuous and significant performance boosts; Rhino languishes with its last release in March '09.
I've seen some work on hacking Rhino:
- Great Thundering Rhinos! presentation from Oracle
- Explore and implement JDK7 InvokeDynamic Google Summer of Code project
But nothing solid about actually merging this code into the project and getting an active committer community around it.
What is the Rhino road map? For example, is there any plan to bring
invokedynamic to the Rhino world?
