java.io.No​tSerializa​bleExcepti​on: com.opensy​mphony.xwo​rk2.inject​.Container​Impl$Const​ructorIn

Hi I have Struts2 application Running on Google App Engine.
When I add "tokenSession" interceptor to any of the actions (say registration.action) , I do get the following exception. If I remove "tokenSession" Interceptor.. things works fine.., what could be the issue?
I have even tried with latest xwork-core-2.3.5-.jar file but no gain.
I use struts2-core.2.3.1.2 and dependent jars. please help me to fix this issue.
