java.io.NotSerializableException on sever restart

[GoogleCodeExporter]

I am very frequently seeing java.io.NotSerializableException on server restart.

What steps will reproduce the problem?
1. Use social login to authenticate
2. After few minutes, restart the server
3.

What is the expected output? What do you see instead?
It shouldn't throw exception.

What version of the product are you using? On what operating system?
4.3 Social spring +Tomcat 7.0.50 + Spring MVC

Please provide any additional information below.

SocialAuthTemplate does not implements Serializable interface. So if you'll try 
to serialize it you may get this error.

Hi Tarun,

Thanks for the comment! 

I don't want to serialize anything. AFAIK, I don't have any code requires 
socialauth returned attributes serialization. 

I was under impression socialauth might be doing this internally, based on your 
comment, it seems socialauth not doing this.

I am using Spring + Tomcat, one of these might be trying to do this. Have you 
come across any such scenario? 

Thank you,

This may be tomcat issue. It seems saveonrestart is true by default. I will 
test and update here if it works. 

Thanks for your time.
