Thanks, I adapted the code to use ScriptUtils.wrap() and encountered a
strange situation where JSON.stringify returns undefined for a valid JS

Here is a reproducer:https://gist.github.com/purplefox/7893408
No, it's not a scope problem. JSON.stringify isn't able to process
ScriptObjectMirror objects, see ll. 263-270 in NativeJSON.java [1].

I see, so when a JS method in one scope is invoked from another scope
all the arguments get automatically wrapped in a ScriptObjectMirror. I
suppose NativeJSON needs to check for ScriptObjectMirror and unwrap
internally before attempting to stringify (?)
I wonder if anyone could suggest a workaround for now? (it's not
obvious to me)
I've managed to work around this for now by not using the JSON impl in
Nashorn but hacking Crockford's pure JS version
<https://github.com/douglascrockford/JSON-js>https://github.com/douglascrockford/JSON-js
and using that.
