Jira issue originally created by user afoeder:

My domain model leads Doctrine to produce an errorneous SQL statement that can be seen here: https://gist.github.com/d12e49ce7f2cbed7f410 This makes MySQL correctly saying "Error Code: 1066. Not unique table/alias: 't5'".
The underlying idea can be seen as attached PNG file.
AbstractParty and AbstractWisher both have @ORM\InheritanceType("JOINED") set.Do the others maybe also require this setting?
