Hi, I've worked around it by using:
ScriptUtils.convert(obj, Map.class) When ever I needed to get a script object as a map or replacing the class with List.class when I need a list... Is that a safe way to do it?

Sorry for an awfully late response, but hope it might still help: Java.asJSONCompatible delegates on the Java side to jdk.nashorn.api.scripting.wrapAsJSONCompatible. It’s part of Nashorn’s supported public API, so it should be fine for you to call it. I’m actually wondering how useful is that API method - you need to pass a “homeGlobal” parameter, and honestly I’m not really sure how you’d obtain that. Maybe Sundar has an idea. Attila. > On 2018.
