Stephan Ewen commented on FLINK-2464:
-------------------------------------

I have seen a similar failure as well. It seems very strange, because that check means that for a buffer, the first 57 bytes are as expected and the 58th is unexpected. And the length is correct as well. I have no idea how that could happen...
