Actually Rhino exposes a "sync" function for this purpose,
org.mozilla.javascript.Synchronizer is just the class implementing this
feature and not meant to be used directly by scripts.
While you could do something like this in Nashorn I would advise against
it. Thread-safety is not one of the primary design goals in Nashorn, and
nowadays most people would agree that there are better and safer ways
for working with threads. I suggest looking at Worker/Actor models where
you have multiple script engines working together through message passing.

Thanks!
Would it be possible to add this to mozilla_compat.js so that "new
org.mozilla.javascript.Synchronizer(myFunction)" would work?

There is a 'sync' function in a demo application (jconsole script
plugin). This may be of use.
var sync = function(func, obj) {
if (arguments.length < 1 || arguments.length > 2 ) {
throw "sync(function [,object]) parameter count mismatch";
}
var syncobj = (arguments.length == 2 ? obj : this);
if (!syncobj._syncLock) {
syncobj._syncLock = new Lock();

} finally {
syncobj._syncLock.unlock();

How does one create synchronized functions in Nashorn?
Rhino has this facility:
function myFunction() { ... }
myFunction = new org.mozilla.javascript.Synchronizer(myFunction)
