Oracle treats empty strings and nulls as equivalent. Insert an empty string, Oracle replaces it with a null.

Our entities were not designed with this in mind. We need to audit their use to ensure:

• empty strings are never inserted into not-null columns
• null values returned from Oracle, through Hibernate, and then back to our code do not cause NPEs
