Matthias Pohl commented on FLINK-33346:
---------------------------------------
The instability is caused by the 100ms. The fatal error hides the actual cause
(the {{TimeoutException}}). It can be reproduced by setting the timeout of the
test to 0ms. The actual cause is revealed when disabling the fatal error
handling or not throwing a AssertionError in case of the fatal error.
