Project Nashorn

Nashorn's goal is to implement a lightweight high-performance JavaScript runtime in Java with a native JVM. This Project intends to enable Java developers embedding of JavaScript in Java applications via JSR-223 and to develop free standing JavaScript applications using the jrunscript command-line tool.

This Project is designed to take full advantage of newer technologies for native JVMs that have been made since the original development of JVM-based JavaScript which was started in 1997 by Netscape and maintained by Mozilla. This Project will be an entirely new code base, focused on these newer technologies. In particular the project will utilize the MethodHandles and InvokeDynamic APIs described in JSR-292.


This Project is sponsored by the Hotspot Group.
