Piotr Nowojski commented on FLINK-25454:
----------------------------------------
I've looked into backporting this fix, but it's not that simple. The fix would
have to be re-implemented, as the code has changed quite a lot between 1.14.x
and 1.15.x. If someone ([~aliazov]? [~akalashnikov]?) would like to pick up
this work, and re-implement [~akalashnikov]'s fix for 1.14 I would be happy to
review it.
