I don't quite get what was happening. Every EO was getting the same GID?

The value stored in the DB field was not too long for an INT and an ALTER TABLE statement changed it without issue. Apparently there something about the process in the JDBC driver or EOF that chokes on it turning a Long into an Integer, but not enough to throw an exception, but enough to make all the values the same, in a non-deterministic way. If I quit and relaunched the app, it would likely repeat a different instance, but not always.
