What it looks like is happening is that the Nashorn load() function does not support Jar URLs.

Partial Solution

It turned out that we had code like:

/** A string giving the full path to the root directory for installed modules. */
var _moduleRoot = Java.type('ptolemy.util.FileUtilities').nameToFile(
'$CLASSPATH/ptolemy/actor/lib/jjs/', null).getAbsolutePath();

[$[Get Code]]

The partial solution was to check for /!:

var __moduleFile = Java.type('ptolemy.util.FileUtilities').nameToFile(
'$CLASSPATH/ptolemy/actor/lib/jjs/', null)

/** A string giving the full path to the root directory for installed modules. */
var _moduleRoot = __moduleFile.getAbsolutePath();

// Check to see if _moduleFile is a Jar URL like
// file:/Users/cxh/ptII/signed/ptolemy/actor/lib/jjs/jjs.jar!/ptolemy/actor/lib/jj
if ( _moduleRoot.indexOf("!/") != -1) {
_moduleRoot = "jar:" + __moduleFile.toString();
}
