> SafetyNetCloseableRegistry is closed prematurely in
> Task::triggerCheckpointBarrier
> ----------------------------------------------------------------------------------

> Key: FLINK-6685
> URL: https://issues.apache.org/jira/browse/FLINK-6685
> Project: Flink
> Issue Type: Bug
> Affects Versions: 1.3.0
> Reporter: Stefan Richter
> Assignee: Stefan Richter
> Priority: Blocker
> Fix For: 1.3.1, 1.4.0
>
>
> The {{SafetyNetCloseableRegistry}} is closed to early in
> {{triggerCheckpointBarrier(...)}}. Right now, it seems like the code assumes
> that {{statefulTask.triggerCheckpoint(...)}} is blocking - which it is not.
> Like this, the registry can be closed while the checkpoint is still running.
