The same (see Utils) regarding r-value is here. For the case with `JsValue&&
jsValue` the call below should be `new JsValue(std::move(jsValue))`.

[sergei, 2017/04/26 14:12:56]

What about it?

-{
-  return env->NewObject(jsValueClass->Get(), jsValueCtor, new AdblockPlus::JsValue(jsValue));
+jobject NewJniJsValue(JNIEnv* env, AdblockPlus::JsValue&& jsValue, jclass jsValueClassArg)
+{
+  return env->NewObject(jsValueClass->Get(), jsValueCtor, new AdblockPlus::JsValue(std::move(jsValue)));

 AdblockPlus::JsValue* JniGetJsValuePtr(jlong ptr)
 {
   return JniLongToTypePtr<AdblockPlus::JsValue>(ptr);

 AdblockPlus::JsValue& JniGetJsValue(jlong ptr)
 {
   return *JniLongToTypePtr<AdblockPlus::JsValue>(ptr);
 }
 
-jobject JniJsValueListToArrayList(JNIEnv* env, const AdblockPlus::JsValueList& list)

[sergei, 2017/04/26 09:21:00]

Here it would be also better to use `JsValueList& list` and below
for (auto& entry : list)
{
  JniAddObjectToList(env, arrayList, *JniLocalReference<jobject>(env,
NewJniJsValue(env, move(entry))));
}

Acknowledged. Now moving in NewJniObject(..){ ... std::move() ... } 

+jobject JniJsValueListToArrayList(JNIEnv* env, AdblockPlus::JsValueList&& list)
 {
   jobject arrayList = NewJniArrayList(env);
 
-  for (AdblockPlus::JsValueList::const_iterator it = list.begin(), end = list.end(); it != end; ++it)
-  {
-    JniAddObjectToList(env, arrayList,
-        *JniLocalReference<jobject>(env, NewJniJsValue(env, *it)));
+  for (AdblockPlus::JsValueList::iterator it = list.begin(), end = list.end(); it != end; ++it)
+  {
+    JniAddObjectToList(env, arrayList, *JniLocalReference<jobject>(env, NewJniJsValue(env, std::move(*it))));
   }
 
   return arrayList;
 }

I think the types of JsValue now are slightly different, but it's fine me.

i wil revert this
