what is the type of args[0]? Can you print args[0].getClass() to check it?
Thanks,

I did try running with -Dnashorn.apply2call=false when I saw the email
for that fix but it did not resolve the issue.
There is no exception thrown, but our JSObject.call method basically
is no-op as a result of not getting a ScriptObjectMirror, it
effectively looks like this:
@Override
public Object call(Object thiz, Object ... args) {
if (args.length < 2 || !(args[0] instanceof
ScriptObjectMirror) || !((ScriptObjectMirror) args[0]).isFunction() ||
!(args[1] instanceof Integer))
return gScriptEnvironment.getUndefined();
// safely cast and call ScriptObjectMirror...
}
I am continuing to work on reproducing it outside our application in a
simple way. In the mean time if there's any other information I can
share besides a reproducing example, or suggestions on workarounds to
try let me know.
Thanks!

Hi,
Sorry for the delayed response. We need more info to debug this - in
particular, what is the exception (if any) thrown etc.
I wonder if this is related to this recent apply-related fix ->
