> Key: FLINK-19264
> URL: https://issues.apache.org/jira/browse/FLINK-19264
> Project: Flink
> Issue Type: Bug
> Affects Versions: 1.12.0
> Reporter: Aljoscha Krettek

> While working on FLINK-19123 I noticed that jobs often fail on {{MiniCluster}} when multiple jobs are running at the same time.
> I created a reproducer here: https://github.com/aljoscha/flink/tree/flink-19123-fix-test-stream-env-alternative. You can run {{MiniClusterConcurrencyITCase}} to see the problem in action. Sometimes the test will succeed, sometimes it will fail with
