org.springframework.integration.ip.tcp.connection.FailoverClientConnectionFactoryTests not passing consistently

The test method that is passing/failing inconsistently is testRealNio.

I first noticed the problem when running the Gradle build from the root of SI. When doing that, the test almost always fails. I then isolated to just this class using -Dtest.single. That will occasionally pass, but not consistently.

When running inside of Eclipse, if I run only the class in question, it will almost always pass. If however, I run all of the tests inside of spring-integration-ip, it will often times fail.

Now here's the killer...last night, when all of this was happening, JIRA was down, so I couldn't file the issue. Now, this morning, I can't get the test to fail (first time that's happened). I will try again in the evening as I have an opportunity to see if this is some sort of time-based issue.

I was able to find this in a browser tab...it is present only when the test fails:

Sorry for the lack of info.
