struts2 - Map is returing Empty{} value for non existing key after Struts migrating from 2.3 to 2.5

Question

We have currently did Struts migration from 2.3 to 2.5.After that facing weird issue with Util Map. This is existing code which is working fine with Struts 2.3.Please find code snippet eg

final Map requestMap = ( Map ) formBean ;

requestMap.get("empname"); ---here empname is non existing key in map

Exceptected result:null

But getting following output

Empty{name='empname'}

Please let me know if anyone aware of this? Really stuck with this issue.
