Yes but the question is does that have to lead to a general war? Perhaps not if they play their cards a little better.
Eventually it has to. Claiming it doesn't makes as much sense as saying Britain doesn't have to go to war against Germany if it invades France. Britain will fight such a war as it can't allow Germany from becoming as powerfull as it would by conquering France. For the same reasons France can't allow Poland to fall to the Germans. They may accept Poland losing its rights in Danzig; control of Pomeralia, even Greater Poland - but not all of Poland which was what Hitler wanted. So even if a "limited war" between Germany and Poland happens, if Poland simply refuses to give up anything (just like OTL) Germany would push on east de facto conquering Poland, thus triggering France to fight the Germans. They can play their hand only as much better as Poland is willing to fold (which isn't much) but one it becomes an "all or nothing" over Poland due to it wanting to fight to the bitter end, if Germany chooses "all" France and Britain choose "war" as they can't accept Germany having "all". And since Hitler is a lunatic who will always go for "all" when it comes to Lebensraum, war is inevitable with him present.
