Application.systemLanguage not working once I use a Java Plugin

Application.systemLanguage returns ‘Unknown’ once I use the simplest java activity inheriting from UnityPlayerActivity. What does Unity do to find out the systemLanguage ?

nevermind, I found this thread. it is a known issue: http://forum.unity3d.com/threads/211227-Unity-4-3-0f4-Application-systemLanguage-returns-Unknown-on-Android
