I've reopened this because its looking like it might actually be in XStream:
I can't be sure, and may actually be a bug in cglib, but it is definitely XStream calling the code that generates the exception.
It may be the way XStream is using cglib and it will need to be verified by a developer.
This should be reproducible with XStream 1.3 and cglib 2.1_3.
