When clases are explicitly listed DataMap complains about duplicate entries

Key: CAY-756
URL: https://issues.apache.org/cayenne/browse/CAY-756
Project: Cayenne
Issue Type: Bug
Components: Cayenne JPA
Reporter: Dain Sundstrom
Assigned To: Andrus Adamchik
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.
