new capacity has to be strictly positive with custom encoder for "piste" ways about graphhopper

We need a small reproducer otherwise we won't be able to investigate it. Also it should target the latest GraphHopper version.

I do not see how the pillar node can be so high for just Europe that the integer overflows .... but you can try to change the version 5.3 and e.g. throw an exception when nextPillarId is negative and/or even better try to merge this PR which avoids early overflow of this integer (integrated in 8.x).

I am trying to rewrite project to 8.0 (btw are there any migration guides between major versions? I could not find any) but I'm pretty sure it will work there because 8.0 is using long.

I am also sure that it has to be integer overflow because there is no code that could change "nextPillarId" to negative. Last log with node count supports this:

Creating graph. Node count (pillar+tower): 3021864391, totalMB:204800, usedMB:157422

Given max int as 2147483647 there had to be overflow in pillar or tower and logs shows that pillar is the one

This is Europe file with 7 encoders and elevation data.

There are no migration guides unfortunately. Feel free to document your process in detail and I'll try to suggest improvements etc so that others can use it as a migration guide.

This should be fixed with #2978
