Matthias Pohl updated FLINK-26122:
----------------------------------
Issue Type: Technical Debt (was: Bug)
> JobManagerMetricGroup.addJob returns null when already being closed
> -------------------------------------------------------------------
>
> Key: FLINK-26122
> URL: https://issues.apache.org/jira/browse/FLINK-26122
> Project: Flink
> Issue Type: Technical Debt
> Components: Runtime / Coordination, Runtime / Metrics
> Affects Versions: 1.16.0
> Reporter: Matthias Pohl
> Priority: Major
>
> We might want to make this more stable by throwing a
> {{IllegalStateException}} instead. The value will be returned to the
> {{JobMaster}} and passed into the scheduler. Additionally, it's called in the
> {{JobMaster}}'s {{stopScheduling}} method where it is closed and would issue
> a {{NullPointerException}} if not properly handled earlier.
