Sure, I will reopen this issue and change the message. Should we remove type + id from the message? Its already in the EntityNotFoundException.

New message could be:

@Message( value = "Returning null (as required by JPA spec) rather than throwing EntityNotFoundException, as the entity does not exist", id = 15013 )

When the exception call stack is displayed, we also show:

javax.persistence.EntityNotFoundException: Unable to find %s with id %s

Should we change the EntityNotFoundException message to use the "(type=%s, id=%s)" style?
