> The flag to prefer checkpoints for recovery introduced in FLINK-11159 returns the wrong checkpoint if:
> * checkpoints are preferred  ({{getLatestCheckpoint(true)}}),
> * the latest checkpoint is *not* a savepoint,
> * more than a single checkpoint is retained.
> The current implementation assumes that the latest checkpoint is a savepoint and skips over it. I attached a patch for {{StandaloneCompletedCheckpointStoreTest}} that demonstrates the issue.
> You can apply the patch via {{git am -3 < *.patch}}.
