MCB java.io.NotSerializableException

Wed Feb 12 14:34:30 EST 2014

I'm glad Scott K spotted this. I assume, Scott, that you aren't using the database-backed storage service. During my MCB testing, I was blaming it for these errors which I was getting as well in Catalina.out. Paul, here's a full dump from my catalina.out from last month when we had the MCB in place in test. Scott, this similar to what you're getting?

Is that expected?

Definitely not expected. I don't think I ever saw it due to all of my Tomcat's explicitly turning off session persistence in context.xml. I am storing info needed during the login session itself, and probably not clearing it out when login is done.

If you can post (or send to me) the full stack trace, it would be useful.
