OpenJPA is an implementation of the Java Persistence API specification.
It is an object-relational mapping (ORM) solution for the Java language,
which simplifies storing objects in databases.
OpenJPA passes the JPA 2.0 TCK, while remaining backwards compatible
with prior releases based on the Java Persistence API (JPA 1.0 - JSR-220).
This package is needed to package Spring Framework 3.0.
