@fabpot yes, this was a short way of using the exception thrown by the `self::validateEntityName` method and transform it into an exception that is relevant for the `validateControllerName` method. The `self::validateEntityName` method throws an exception like: `'The entity name must contain a : ("..." given, expecting something like AcmeBlogBundle:Blog/Post)` this will transform it into `'The controller name must contain a : ("..." given, expecting something like AcmeBlogBundle:Post`

But now I see this code, I think it is nicer to make a new exception message here instead of replace the previous message?
