I agree with Alan. Java shouldn't forcibly create the user directory if 
it doesn't exist yet. I suggest to pass 0 (zero) as the dwFlags argument 
to ::SHGetKnownFolderPath(). The same applies to a call to the 
::SHGetFolderPathW(). getHomeFromShell32() may return NULL, so let it do 
so if no user directory exists.
