Arvid Heise commented on FLINK-19925:
-------------------------------------
Not sure what additional information I should provide [~kevin.cyj] - I simply
used the line numbers of the stacktrace to backtrack what caused the ultimate
exception. But I have no clue about the actual cause, e.g. why
{{clientHandler}} is null.
