Where is current wallpaper stored on Jellybean?

On my Nexus S running 4.1.1, I am unable to find where the current wallpaper is stored. I referred to https://android.stackexchange.com/questions/18450/where-is-the-background-image-saved , but my /data/data/com.android.settings/files folder is empty (I do have my file browser showing hidden files). It was confirmed in that question that ICS stored it in that location, but did Jellybean move it to a different place?
