Till Rohrmann commented on FLINK-23417:
---------------------------------------
I think the problem is a race condition between the startupPeriod of the
{{ResourceManager}} and the slot request. The test assumes that the slot
request times out but if the startup period has passed earlier (in fact it is
the same timeout value), then the request is failed with a different exception.
