Quick update for FLINK-9676: It is not super critical/blocker to fix this issue for Flink 1.5.1 since the deadlock only occurs in case of a task cancellation and also then we haven't seen it to happen too often. If Flink should deadlock, then there is still the TaskCancelerWatchDog which would kill the TM process if the cancellation takes too long. Having said this, it is still important to fix this issue but imo it is not a release blocker.
Nico is currently looking into it. Maybe we have a fix for it this evening or it will be included in Flink 1.5.2.
