Could not passivate; failed to save state in JBoss EAP

We are migrating our application from Websphere 6.1 to JBoss EAP 5.0.

When the ejbPassivate() method is called during the life cycle of the statefull session bean, we are getting the following error :

WARN  [org.jboss.ejb.plugins.AbstractInstanceCache] (Timer-2) failed to passivate, id=gp1mql4e-bcq

But when we run the same code on Websphere 6.1 we are not getting the above mentioned error.

We have checked

com.xxx.core.data.terms.DateTerm

is not implementing Serializable interface and according to the J2EE EJB specification non static fields of the stateful session bean should implement Serializable interface.

We are just wondering how it works with websphere 6.1.

Is it a bug in websphere or are we missing something here?

Any help would be appreciated.
