-----------------------------------------
Chris suggested:
----
I vaguely recall that this kind of stack trace can happen with certain
combinations of IPv6 enabled and the host OS doing unexpected things in
the entry for the loopback address in /etc/hosts. (Java parses /etc/hosts
as part of looking at the network interface information.) Sorry, but I
don't remember the specifics.
Hadoop runs its tests with -Djava.net.preferIPv4Stack=true. Maybe we
should try the same?

> We're seeing some failing jobs (see below) and the speculation is that it
> might be due to ipv6 vs ipv4 usage. It would be nice to turn on "prefer ipv4"
> in the jvm but there is no easy way to do that. I'll propose that we add a
> variable to ant that's passed through to the jvm.

> This is very odd. It failed 2 of the last three times it was run on H9
> with the following:
> 2016-03-20 06:06:18,480 [myid:] - INFO
> [main:JUnit4ZKTestRunner$LoggedInvokeMethod@74] - TEST METHOD FAILED
> testBindByAddress
> java.net.SocketException: No such device
> at java.net.NetworkInterface.isLoopback0(Native Method)
> at java.net.NetworkInterface.isLoopback(NetworkInterface.java:339)
> at
> org.apache.zookeeper.test.ClientPortBindTest.testBindByAddress(ClientPortBindTest.java:61)
> https://builds.apache.org/job/ZooKeeper_branch34/buildTimeTrend
> Why would it pass one of the times though if there is no loopback
> device on the host? That seems very odd!
