What do you mean, exactly, by "internal class"?  Can you show the code 
that calls JS_NewObject and stores its return value?

There is no such API, nor should there be in a GC'd runtime's API.

You have to tell the engine when you no longer have an "internal class" 
referring to the object returned from JS_NewObject.  See JS_RemoveRoot, 
which implies you have already called JS_AddNamedRoot passing the 
address of a pointer to the JSObject.  The pointer's storage must remain 
live till you call JS_RemoveRoot, of course.
