Nico Kruber commented on FLINK-13020:
-------------------------------------
Actually, I just encountered this error in a branch of mine which is based on
[latest
master|https://github.com/apache/flink/commit/428ce1b938813fba287a51bf86e6c52ef54453cb].
So either there has been a regression, or the fix does not work in all cases,
or it is no duplicate afterall:
