[x3d-public] node-X3DJSAIL showing same problem as PyJNIus?

[John Carlson]

node-X3DJSAIL fails on setName return value.   Same issue as PyJNIus
possibly.  Nashorn does NOT show same problem with near equal code.

Suggestions (alternatives):

Use Nashorn for JavaScript interfacing with X3DJSAIL, use different coding
style in NodeSerializer.js/XSLT, use X_ITE for SAI (not tested and
generation isn't complete yet, need to change sets/adds to property
access--possibly), hope and pray that Nashorn isn't buried, and/or is
maintained in OpenJDK or otherwise opensourced, fix contract violation in
X3DJSAIL, or complain to node-java developers.

Recommendation: Move towards X_ITE solution for SAI for now.  Test a few
individual cases in browser, generate HTML around generated JavaScript code
to make it VRMLScript.   Create VRMLScriptSerializer.js based on
node/JavaScriptSerializer.js (SAI version).   Create a vrmlscript folder
for project on sourceforge.

Future:   Work towards supporting VRMLScript in X3DOM, possibly based on
X3DJSONLD's Script*.js program.

X3DJSAIL Interfaces:

MetadataSetObject.java: public final MetadataSetObject setName(String
newValue)
MetadataSetObject.java: public MetadataSetObject setName(SFStringObject
newValue)
../../sai/Core/MetadataSet.java:        public MetadataSet setName(String
newValue);
