Description
RocksDBCheckpointDiffer has single instance per DB, which may cause failure if MiniOzoneCluster reuses the same directory between runs. Apparently this can happen if cluster is started in @BeforeAll method and test is repeated due to @Flaky annotation. The result is that if the first run fails, repeated attempts always run into the error.
