Are you sure you updated from the git master (fetch and merge)?
As for example:
Note that this has been updated to Notification_BAs, while your trace still shows:
Unsuccessful: drop table Notification_BusinessAdministrators cascade constraints

The issues related to Oracle have been resolved in the SNAPSHOT code.
