Patrick Linskey commented on OPENJPA-266:
-----------------------------------------

Agreed. Additionally, it is already trivial for vendors to repackage OpenJPA with different dbdictionaries. All you need to do is create a ProductDerivation that changes the aliases listed in the JDBCConfigurationImpl.dbdictionaryPlugin.

See JDBCPersistenceProductDerivation for an example of a product derivation that changes alias settings.

> This kind of modification is not adding any functionality but making OpenJPA classes subclassable.
