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.

> Add Extensibility: Change "private" field/method to "protected" or "public"
