Unpack in www.web3d.org/x3d/stylesheets/java
License.txt is under nashorn. There’s an apache license, an MIT license (optionally LGPL), a Web3D license, and a CC Share alike license. The share alike is my best guess at what’s at MDN. The webpage that I pulled the code from is referenced. I don’t know how to find a link to the license from that page, so I just googled something like Mozilla license and found the share alike license for the wiki. If you have a better spot on the Mozilla license from the web page, go ahead and replace the license in the license.txt.
When nashorn gets String.prototype.repeat (Java 9, I hope), we should be able to remove the Mozilla license.
Xmldom is pretty vital to any DOM manipulation. There may be an alternate implementation in Nashorn.
Jvm-npm.js is an implementation of require (and we may need it to load javascript objects from a jar—I may have removed that. The package is under npm, jvm-npm, but not in package.json as I have modified it).
Let me know if you have any more difficulties.

My guess is you are missing java/nashorn/jvm-npm.js. I will send you the zip of nashorn.

I have a stock setup for JDK1.8 and Ant. Haven't configured anything with rhino or nashorn.
Looking at manual for Ant script task and stackoverflow offered some ideas but no explicit fix:
https://ant.apache.org/manual/Tasks/script.html
Experimented with changing
<script language="nashorn">
to
<script language="javascript" manager="javax">
... which got farther. Checked in that variant, kept old form as a comment in build.xml.
This changed the run-time exception to something nashorn-related, at least. Not seeing what is wrong now however.
