public static Object unwrap(Object object) {
    // Nashorn creates these mirrors when they pass through certain
    // boundaries. However, we are only allowed to unwrap them from the same
    // global context in which they were wrapped. We will try to unwrap them
    // here, but if that doesn't work we will just create a shallow clone.
    // The clone won't function like the original, but will be good enough
    // for our purposes here.

    object = ScriptObjectMirror.unwrap(object, Context.getGlobal());
    if (object instanceof ScriptObjectMirror) {
        ScriptObjectMirror scriptObjectMirror = (ScriptObjectMirror) object;
        ScriptObject scriptObject = NashornNativeUtil.newObject();
        for (String key : scriptObjectMirror.getOwnKeys(true)) {
            Object value = scriptObjectMirror.get(key);
            scriptObject.put(key, value, false);
        }/*from  w  w w  .  ja v a2s.  c  o  m*/
        object = scriptObject;
