I recently upgraded to RC9 and some of my queries that contain LEFT JOIN FETCHES to lazy load relationships are now failing. For example, the following query:


  | SELECT c FROM Campaign c "
  | "LEFT JOIN FETCH c.states "
  | "LEFT JOIN FETCH c.dmas "
  | "LEFT JOIN FETCH c.ads "
  | "LEFT JOIN FETCH c.dayParts "
  | "LEFT JOIN FETCH c.adSlots "
  | "WHERE c.id = :id 
  | 

is now throwing the following exception:

If I grab the raw SQL, it definitely is coming back  with 4 result where previously in RC8 there was only 1 result. 

Is this expected behavior or a bug? 

Thanks,

Scott
