Hi to all,
we tried to upgrade our jobs to Flink 1.6.2 but now we get the following
error (we saw a similar issue with spark that was caused by different java
version on the cluster servers so we checked them and they are all to the
same version - oracle-8-191):

Has anyone faced this problem before? How can we try to solve it?
Best,Flavio
