>             Project: Flink
>          Issue Type: Bug
>          Components: Runtime / Configuration, Runtime / REST, Runtime / Web Frontend
>    Affects Versions: 1.19.1, 1.20.5
>         Environment: Reproduced locally with Apache Flink 1.20.5 and 1.19.1 using a MiniCluster and the real Dashboard Job Configuration page. The same issue was not reproducible in Apache Flink 1.18.1.
> Evidence screenshots are available for 1.20.5 and 1.19.1.

> When a job is configured with restart-strategy.type=fixed-delay and related restart-strategy.fixed-delay.* options, the runtime uses the job-level restart strategy correctly. However, the Dashboard Job Configuration page and the /jobs/<jid>/config REST
>  
> !image-2026-07-14-11-30-18-947.png! response display "Cluster level default restart strategy".
> This is reproducible in Flink 1.19.1 and Flink 1.20.5 LTS. I also checked Flink 1.18.1, where the same issue is not reproducible.
> Example job-level configuration:
> - restart-strategy.type = fixed-delay
> - restart-strategy.fixed-delay.attempts = 10
> - restart-strategy.fixed-delay.delay = 1 min
> Expected:
> The Job Configuration page and the /jobs/<jid>/config REST response should display the configured fixed-delay restart strategy.
> Actual:
> The Job Configuration page and the /jobs/<jid>/config REST response display "Cluster level default restart strategy".
> This looks like a regression introduced by the restart strategy configuration migration in Flink 1.19: runtime scheduling reads RestartStrategyOptions from Configuration correctly, but ArchivedExecutionConfig still derives the displayed restart strategy from ExecutionConfig#getRestartStrategy(), which returns the fallback restart strategy.
> I searched existing FLINK issues with keywords including "Cluster level default restart strategy", "ArchivedExecutionConfig", "restart-strategy Dashboard", "Job Configuration restart strategy", and "RestartStrategyOptions ArchivedExecutionConfig", but did not find an existing issue for this Dashboard display problem.
