          Issue Type: Bug
            Reporter: Thibault Falque


Hi,
During a classroom we have noticed a bug when use the "TABLE PER CLASS" for inheritance strategy. 

I have create three classes: Computer, Desktop and Gamer. Gamer extends Desktop that extends Computer. 

I have a desktop and a gamer computer in the database. For the request "SELECT g FROM Gamer g" the system returns 2 computers but the correct answer should be 1. 


I attached the source code with the unit tests. It is a drive link because I can't uploaded compressed files: https://drive.google.com/open?id=0B7j65u7m8zmeY2pRY0JDZE55S1U 

Thanks for your help.
Thibault.
