>          Issue Type: Bug
>          Components: Runtime / Task
>    Affects Versions: 1.13.0
>            Reporter: Robert Metzger
>            Assignee: Robert Metzger

> In FLINK-15156, we introduced a feature that allows users to log or completely disable calls to System.exit().
> This feature is enabled for certain threads / code sections intended to execute user-code.
> However, some user code calls might still lead to fatal errors, which we want to handle by killing the Flink process.
> It is likely that this new change (which is disabled by default) can lead to a situation where Flink should exit immediately, but it doesn't (thus leaving the system in an inconsistent state)
