Could not load java.util.Iterator on RequestAppender

Every now and then I get the following exception when running a web application. Not sure if this issue is a local issue on this machine. I got the following trace after I deployed an app x to a tomcat instance that hasn’t started any apps yet but had x already deployed before.

Closing this issue until I get the same exception on the same class. Not completely sure if the error was on RequestAppender previously.
