Yes, @BratwurstBoy, it is a confimation of common border between Poland and Germany. Yet, it has nothing to do with war reparations.
You obviously don't think that this would stick in the international court, do you?
The reason why there's no bilateral Polish-German treaty is due to our difficult modern history which prevented Poland (and Germany too) for almost half a century to conduct independent international realtions. Now there's a chance to regulate it properly.
Again show me your seriousness and ask Moscow for reparations...
It's not wise to pick up a fight with two strong opponents at the same time (as you should know by now). It's better to deal with them one by one. It is also wise to pick a fight in the most appropriate moment and place when you have a chance to do so.
