The org.apache.openjpa JPA packages are not available to JPA applications that
use the WebSphere traditional or Liberty Java EE 7 JPA 2.1 implementation.
When you migrate to JPA 2.1, remove references to the org.apache.openjpa APIs from your application.
For maximum portability, use the standard
javax.persistence APIs where possible.
For information about EclipseLink APIs that you can use instead of the OpenJPA APIs, see the
EclipseLink 2.6.0, API Reference.
