    [hotfix] [tests] Reduce visibility of helper class methods
    There is no need to make the helper methods public. No other class
    should even use this inner test helper invokable.

    [FLINK-7067] [jobmanager] Resume periodic checkpoints after failed cancel-job-with-savepoint
    Problem: If a cancel-job-with-savepoint request fails, this has an
    unintended side effect on the respective job if it has periodic
    checkpoints enabled. The periodic checkpoint scheduler is stopped
    before triggering the savepoint, but not restarted if a savepoint
    fails and the job is not cancelled.
    This commit makes sure that the periodic checkpoint scheduler is
    restarted iff periodic checkpoints were enabled before.
    This closes #4254.

    [FLINK-7067] [jobmanager] Backport to 1.3

>             Project: Flink
>          Issue Type: Bug
>          Components: State Backends, Checkpointing
>    Affects Versions: 1.3.1
>            Reporter: Ufuk Celebi
>            Assignee: Ufuk Celebi
>            Priority: Blocker
>             Fix For: 1.4.0, 1.3.3
> The `CancelWithSavepoint` action of the JobManager first stops the checkpoint scheduler,
then triggers a savepoint, and cancels the job after the savepoint completes.
> If the savepoint fails, the command should not have any side effects and we don't cancel
the job. The issue is that the checkpoint scheduler is not restarted though.
