Ok turns out this morning when I restarted the server, it started working.
The things I had changed was the return type for newSession in
WebApplication to be NeobitsWebSession and return type of the following
covariant method also to be NeobitsWebSession. I suppose thats how it
supposed to be - can someone confirm? also not sure why it was only throwing
exception during back button and not during normal browsing of the site in
forward direction.
I think the reason why this change didnt work yesterday was probably because
of the serialization, for some reason the serialization doesnt seem to
detect the new version of the class a lot of the times and I have to either
delete the session.ser file under tomcat or restart the tomcat server from
scratch to make it see the new classes.
