An update incase anyone else has this problem. It looks like an issue with competing log4j configurations that could be resolved by using Logger Repositories. I've updated a thread in the brisk user group http://groups.google.com/group/brisk-users/msg/619b5ebba2fb0e89
Has anyone else had this problem ?
