[jira] [Commented] (FLINK-6685) SafetyNetCloseableRegistry is closed prematurely in Task::triggerCheckpointBarrier

["Stefan Richter (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FLINK-6685?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16021192#comment-16021192 ] 

Stefan Richter commented on FLINK-6685:
---------------------------------------

For the release, we can fix this by reusing the registry from the task scope and not closing it on a per-checkpoint scope.

In the future, we should fix this properly by implementing the changes suggested in FLINK-6684.

> 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.
