OK understood now. First some background:
1. Ant classpath is supposed to be colon/semicolon agnostic, regardless of operating system.
https://ant.apache.org/manual/using.html
2. You own the nashorn subdirectory tree so you can do anything you want there. I can followup by confirming elsewhere.
3. I am running
don at it154928 ~
$ java -version
java version "1.8.0_172"
Java(TM) SE Runtime Environment (build 1.8.0_172-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.172-b11, mixed mode)
4.I went into that build.xml and changed entries like
classpath="${java.classes.dir};${java.jars.dir}/${jsai.full.archive.jar.name}
to
classpath="${java.classes.dir}:${java.jars.dir}/${jsai.full.archive.jar.name}
5. That change had no effect on output of build.xml test.nashorn, copy follows

X3DJSONLD was eliminated from the problem by printing out the DOM object, and verifying the Viewpoint objects were there.
