/**
 * This class was added so we can create sockets without options that were
 * needed for server sockets. It just overrides create so that we call new
 * natives which only set the options required for plain sockets. In order to
 * preserve behaviour of older versions the create PlainSocketImpl was left as
 * is and this new class was added. For newer versions an instance of this class
 * is used, for earlier versions the original PlainSocketImpl is used.
