I'm not convinced my hunch was correct anymore, now that I've seen the API... Rhino should already have been selecting the correct overloaded method. You should be able to verify that in your full stacktrace.
Assuming that's the case, I can't think of any other obvious problems. I'd try looking through the full stacktrace and narrow down the exact location of the ClassCastException, it may give you an idea of what is trying to be casted to what unsuccessfully and help you narrow down the issue. It's possible that the problem is elsewhere in your code when you're assembling the request object or something like that. If you still can't get this working in JS you could try putting that block of logic in a separate Java helper class method and just calling that method with the appropriate input values; that should avoid the issues arising from Rhino's runtime type resolution. Or you could move to JavaFlow if you'd rather go that way.
