I vaguely remember the history of this issue (Michael will know 
better),  but the expectation from the API is that while empty string 
is not disallowed if the display name cannot be retrieved then null 
should be returned.

I think such a clarification is unnecessary in the API, it is such a 
corner case, and may be confusing.
If the empty string is not allowed then changing the @return to make 
this clear would be good.
