Piotr Nowojski commented on FLINK-19539:
----------------------------------------
I've seen the issue a couple of days ago a couple of times on my WIP branch, so
this failure is on the master since at least a couple of days [~chesnay]. I
didn't report it back then as I was having quite a bit of other test failures
that were caused by my changes, and only now I finally ended up with just this
one often failure. Example instances:
