Thank you for your question!

I don't think there is an easy way to give per-method access. Could you create a new class XYZProxy add the class you want to call the methods on as a private variable and then add to XYZProxy the methods you would like to expose?

I should be able to create it;But some method in parent class is exposed to javascript;Such as wait() method;

I think some methods such as wait()、notify(),are exposed to javascript is not security.Thread safety issues may arise.Thank you for your attention.

Ah good point! The sandbox does not provide any methods as far as I remember to prevent access to those!

If you do find a way, please let me know & we may be able to add that into the sandbox!
