Looking at the stack trace, Tomcat's WebappClassLoader couldn't find the class
and  delegated to the parent class loader. It is an instance of
java.net.URLClassLoader that is loading the class.

Given it is the JVM that is loading the class, this looks like a synchronisation
(or rather lack of synchronisation) issue with the JVM. A quick check of the JVM
source suggests this is likely since I can't see any synchronisation at all.
