[GraphHopper] should GraphHopper stop to use assert?

[Peter]

Hi John,

asserts are checked automatically when running the tests via maven, so
they are of some use there. And in critical code like DataAccess which
is called many many times in routing we need to avoid overhead which is
why we use asserts there. But I agree completely that always exceptions
should be used. Maybe you can try to replace with if statement +
exception and see if this has an impact on performance?

Kind Regards,
Peter
