As long as you are redeploying the entire EAR (which you seem to be doing correctly), there should not have been a ClassCastException. Unfortunately, i don't have a Linux setup where i can try to reproduce this myself. So i won't be of much help in debugging this. Maybe someone who has a Linux system will be able to help you.
