/**
* {@link org.springframework.orm.jpa.JpaVendorAdapter} implementation for Eclipse
* Persistence Services (EclipseLink). Developed and tested against EclipseLink 2.7;
* backwards-compatible with EclipseLink 2.5 and 2.6 at runtime.
*
* Exposes EclipseLink's persistence provider and EntityManager extension interface,
* and adapts {@link AbstractJpaVendorAdapter}'s common configuration settings.
* No support for the detection of annotated packages (through
* {@link org.springframework.orm.jpa.persistenceunit.SmartPersistenceUnitInfo#getManagedPackages()})
* since EclipseLink doesn't use package-level metadata.
