unit tests deliver "cannot listen to UDP port ..." is this ok ?

[Luca Toldo]

Dear JenkinsDevs,

I am trying to extend the https://github.com/jenkinsci/hashicorp-vault-plugin 

with a "write to vault" capability. 

Actually, is really little work since the *real* part is done by the underlying java driver   https://github.com/BetterCloud/vault-java-driver.

Anyhow, is good practice of doing unit tests, and what I am facing now is that by running the unit tests provided by the hascicorp-vault-plugin I keep getting  the following line in the log

 INFO hudson.UDPBroadcastThread#run: Cannot listen to UDP port 33,848, skipping: java.net.SocketException: Can't assign requested address (local port 33848 to address 0:0:0:0:0:0:0:0, remote host unknown)

It looks to me as if it is just an INFO however I would like to know 

a) if is just INFO and has no practical impact on the meaning of the error

b) how to suppress it

thanks !

It is.

Use a more recent `jenkins.version`.
