ferenc-csaky opened a new pull request, #21127:
URL: https://github.com/apache/flink/pull/21127
## What is the purpose of the change
Fixes a comparator related bug for `flink list`, which can occur in JDK8.
Probably fixed with JDK9, but I did not validated that.
## Brief change log
Removed the custom comparator for `JobStatusMessage` and replaced it with a
safe `Comparator.comparing(...)`.
## Verifying this change
If we put back the removed custom comparator, the updated test with the
tricky data will fail.
