It failed a few times in Jenkins lately. Example:
Expected: [] Actual: 
junit.framework.AssertionFailedError: Expected: [] Actual:  at org.apache.cassandra.distributed.shared.AssertUtils.assertRows(AssertUtils.java:58) at org.apache.cassandra.distributed.test.FqlReplayDDLExclusionTest.test(FqlReplayDDLExclusionTest.java:102)
I was also able to reproduce it locally on the latest 4.0.0 so I believe it is worth it to be checked.
//CC stefan.miklosovic and bereng as I see you two are the only people who worked on that test up to now so If you have any thoughts to share, as usual, that will be highly appreciated
