Am I missing anything?

Answer 1

this seems to only happen on MacOS. the problem is in jmDNS library: https://github.com/openhab/jmdns/issues/12

the specific bug filed against Jenkins is https://issues.jenkins-ci.org/browse/JENKINS-25369

it has since been fixed in the library source code (https://github.com/openhab/jmdns/pull/16/files , February 2015) but it is not included in the current Jenkins (as of July 2015).

as a workaround, you can start Jenkins like this:

java -Dhudson.DNSMultiCast.disabled=true -jar jenkins.war
