> in FLINK-31593 we discovered a instability when generating the test data for
> {{StatefulJobSavepointMigrationITCase}} and
> {{StatefulJobWBroadcastStateMigrationITCase}}. It appears that files are
> deleted that shouldn't be deleted (see [~Yanfei Lei]'s [comment in
> FLINK-31593|https://issues.apache.org/jira/browse/FLINK-31593?focusedCommentId=17706679&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-17706679]).
> It's quite reproducible when generating the 1.17 test data for
> {{StatefulJobWBroadcastStateMigrationITCase}} and doing a test run to verify
> it.
> I'm attaching the debug logs of such two runs that I generated for
> FLINK-31593 in this issue as well.
