Raw types warning

[Brian Goetz]

That's going pretty roundabout...

How about:

   hqIds.stream()
        .map(id -> findDealer(id))
        .flatMap(d -> d.getBranches().stream())
        .collect(toList());

No reason to create intermediate garbage List<Dealer> if you can 
efficiently map from id to Dealer.
