The org.eclipse.persistence.internal.jpa.deployment.JPAInitializer

    protected SEPersistenceUnitInfo findPersistenceUnitInfoInArchive(String puName, Archive archive, Map m){
        Iterator<SEPersistenceUnitInfo> persistenceUnits = PersistenceUnitProcessor.getPersistenceUnits(archive, initializationClassloader).iterator();
        while (persistenceUnits.hasNext()) {
            SEPersistenceUnitInfo persistenceUnitInfo = persistenceUnits.next();
            if(isPersistenceProviderSupported(persistenceUnitInfo.getPersistenceProviderClassName()) &&  persistenceUnitInfo.getPersistenceUnitName().equals(puName)) {
                return persistenceUnitInfo;
            }
        }
        return null;
    }

This method should allow the javax.persistence.provider property in the map to override the value specified in the persistence.xml.

Within the while loop the code should look like:

SEPersistenceUnitInfo persistenceUnitInfo = persistenceUnits.next();

String providerClassName = persistenceUnitInfo.getPersistenceProviderClassName();

if (m.containsKey("javax.persistence.provider")) {
    providerClassName  = (String) m.get("javax.persistence.provider");
}
 
           if(isPersistenceProviderSupported(providerClassName ) &&  persistenceUnitInfo.getPersistenceUnitName().equals(puName)) {
                return persistenceUnitInfo;
