Cannot resolve Struts2 NotSerializableException even after update to 2.3.12

Question

I currently doing a work with struts2 and this error suddenly appears. Some cache of my objects is not working.

I use JBoss 5 and struts2 : struts2-core-2.3.4.1.jar xwork-core-2.3.4.1.jar

The stack trace is here : http://pastebin.com/QpPV01wX

this is some snippet :

I would love suggestions or might be something wrong I did.

Thank you very much in advance,

** UPDATED

I tried to remove token session interceptor that I used in my struts.xml and the problem is gone. Still, I dont know why it went wrong if I use token. At least in my case, it is solved by removing token session interceptor.

I remove following line on struts.xml

<interceptor-ref name="tokenSession">
  <param name="excludeMethods">list</param>
  <param name="includeMethods">save,update</param>
</interceptor-ref>

Seems you have put Objects into the cache or your session that do not implement java.io.Serializable.
