I see that this test is flaky on the Apache Jenkins as well. It fails from
time to time... (e.g.
https://builds.apache.org/view/ZK%20All/job/zookeeper-master-maven/557/org.apache.zookeeper$zookeeper/testReport/org.apache.zookeeper.server/NettyServerCnxnFactoryTest/testOutstandingHandshakeLimit/
)

I will create a Jira ticket and take a look. Or if someone is already
working on it, then please let me know...

Cheers,
Mate
