No, I meant simply define a plain Java class, but with Java
constructor with Java varargs:
public class Foo {
public Foo(Object... arguments) { ... }
}
Then wrap Foo objects with
org.mozilla.javascript.Context.javaToJS(fooObject).
(Incidentally, you should be able to define JavaScript constructors
using jsConstructor if you use ScriptableObject.defineClass to process
the class. But the way I outlined above is much easier.)
