Hibernate attempts to read an invalid column from the collection result set when the following conditions are present:

1. Instances of a subclass are contained in a collection
2. The subclasses are single-table + a <join> (table-per-subclass with discriminator)
3. The <join> portion of the subclass contains at least 3 of its own columns
