Bug fix:

Hibernate only supplies *mapped* entities, but if a mapped entity has an abstract unmapped ancestor, this ancestor would not be discovered and loaded, thus compromising the initial load premise that all superclasses are loaded for every initial load entry. Added logic that fills the potential gap.
