exploit scanner warns that jquery.js has malicious code

Hi
Today I had to run a wordpress plugin called exploit-scanner(searching for exploits). It warned me about a snippet of code inside wp-includes/js/jquery/jquery.js. It points to this code
n(a,b,c){var d="0x"+b-65536;return
I cant find this code in jQuerys recent versions. I also checked WordPress 4.1 and this code is still there. I can’t read this compressed version 🙂 Is it a forked version of jquery? What does this code do?
