> If "kodo.persistence.PersistenceProviderImpl" is specified instead of "org.apache.openjpa.persistence.PersistenceProviderImpl", a misleading error message results that suggests that the persistence.xml file is missing or cannot be found.

>      [java] Exception in thread "main" java.util.MissingResourceException: org.apache.openjpa.persistence.PersistenceProductDerivation:java.util.MissingResourceException: The specified XML resource "META-INF/persistence.xml" for persistence unit "null" can't be found in your class path.
