Hm, doesnt seem to work for the first try. What I did is I updated the
client with the new jar based on your backport branch. Redeployed the job with
a savepoint (to get the new Flink version), took a savepoint and tried to
redeploy with the changed topology.
I still seem to get the same error.
Is it possible that the previous checkpoints have an effect on this? In any
case I will double check tomorrow morning and try to do the test again.
