[jira] [Commented] (FLINK-16145) ScheduledUnit toString method throw NPE when Execution is null

    [ https://issues.apache.org/jira/browse/FLINK-16145?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17040582#comment-17040582 ] 

Zhu Zhu commented on FLINK-16145:
---------------------------------

Thanks for reporting this issue [~liuyufei]!
This is a bug since {{vertexExecution}} is nullable while {{toString()}} always invokes {{vertexExecution.getVertexWithAttempt()}}. It does not cause production problem though at the moment.
{{vertexExecution}} is also causing some other problems so I'm planning to replace it with an ExecutionVertexID (see FLINK-16180). That would also fix this potential issue.
