Poland is not right next to Romania on any current maps that I have found.
Poland is bordered by Lithuania and Russia to the northeast, Belarus and Ukraine to the east, Slovakia and the Czech Republic to the south, and Germany to the west.
Romania does border Ukraine, however if you were to travel from Ukraine to Romania the best route is actually through Slovakia and Hungary.
