[x3d-public] X3DJSAIL, X3dToJava.xslt and DOM X3DLoaderObject testing: anotherClassCastException

[John Carlson]

Previously reported problem, now assigned to the X3DLoaderObject, I believe.

No Viewpoint children in X3D or JSON output.  Is a problem with X3DLoaderObject, looks like another class cast exception.  X3DJSONLD was eliminated from the problem by printing out the DOM object, and verifying the Viewpoint objects were there.   See x3d-code/www.web3d.org/x3d/stylesheets/java/nashorn/examples/Quotes.js.

Can be regenerated by running `ant test.nashorn` in x3d-code/www.web3d.org/x3d/stylesheets/java

See output in nashorn/examples/Json.{json,x3d}
