Duplicate Persistence Unit error msg?

Question

Deploying my ear on Weblogic 10 has given me a strange error. It is saying that I am deploying two Persistence Units with the same name, even though I only have one Persistence Uni. As you can see from the stack trace, it's complaining about the same jar for the "First PU and Second PU", even though this jar only has one persistence.xml file. How is this possible?
