Description

The enhancer seems to need to have all classes explicitly listed in the persistence.xml file. I would expect the enhancer to enhance any class that has mapping metadata or if exclude-unlisted is false any class with @Entity annotation. Anyway, I listed my classes in the persistence unit, but then I get the following exception:

java.lang.IllegalArgumentException: An attempt to override entity 'Employee

You can reproduce this with the openejb JpaTest; just change the provider at the top of the test to cayenne.
