Message:

Master version of the [DDC-3863](http://www.doctrine-project.org/jira/browse/[DDC-3863]%28http://www.doctrine-project.org/jira/browse/DDC-3863%29)'s fix. Basically, instead of returning an empty array() value if the value is null (or empty), we're returning another null value instead.

If you think this is a valid addition (after some corrections if needed), should I open other PRs for the other supported branches (2.3, 2.4, 2.5) ?

Thanks
