Patrick Hunt commented on ZOOKEEPER-1441:
-----------------------------------------
I see in the most recent failures:
https://builds.apache.org/view/S-Z/view/ZooKeeper/job/ZooKeeper-trunk-java11/155/testReport/junit/org.apache.zookeeper.test/FollowerResyncConcurrencyTest/testResyncByDiffAfterFollowerCrashes/
The following sequence (extracted from the larger log):

java.net.BindException: Address already in use
{noformat}
I updated that job to not use parallel test threads and the issue still happens:
https://builds.apache.org/view/S-Z/view/ZooKeeper/job/ZooKeeper-trunk-java11/156/testReport/junit/org.apache.zookeeper.server/ZxidRolloverTest/testRolloverThenLeaderRestart/
so it's not related to "test.junit.threads=1"
It seems like it may be a real issue with some change in java11 semantics
around sockets?
Has anything else been updated that could be related? java10 with the same code
seems fine.
> Some test cases are failing because Port bind issue.
