This Project intends to enable Java developers embedding of JavaScript in Java applications via <a href="https://jcp.org/en/jsr/detail?id=223">JSR-223</a> and to develop free standing JavaScript applications using the <code><a href="https://docs.oracle.com/javase/7/docs/technotes/tools/share/jrunscript.html"> jrunscript</a></code> command-line tool.</p> <p>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 <code><a href="https://docs.oracle.com/javase/7/docs/api/java/lang/invoke/MethodHandles.html"> MethodHandles</a></code> and <code><a href="https://docs.oracle.com/javase/7/docs/api/java/lang/invoke/package-summary.html"> InvokeDynamic</a></code> APIs described in <a href="https://jcp.org/en/jsr/detail?id=292">JSR-292</a>.</p>
