openjpa.jdbc.MappingDefaults: DefaultMissingInfo=false
This tells the MetaDataDefaults (the thing responsible for populating
metadata and mappings with information when nothing is provided) not
to generate defaults in the spec-proscribed way. I believe that if you
set this option, you will also need to explicitly run the mappingtool
on your classes prior to deploying them so that the mappingtool can
explicitly record the mapping values.
