Not sure, I also get a reproducible `EOFException` from `mock-slave`
tests. Kohsuke agreed something was wrong but the conversation stopped
there.

EOFException when terminating slaves programatically

[Carlos Sanchez]

Hi,

While writing the Kubernetes plugin, a plugin to dynamically start slaves 
in Kubernetes (something similar to the Docker one) I am getting 
EOFException when deleting the Pod (the container running the jenkins-slave 
jar)

The code for _terminate

cloud.connect().deletePod(name, cloud.getNamespace());
LOGGER.log(Level.INFO, Terminated Kubernetes instance for 
slave {0}, name);
toComputer().disconnect(OfflineCause.create(new 
Localizable(HOLDER, offline)));
LOGGER.log(Level.INFO, Disconnected computer {0}, name);

https://github.com/jenkinsci/kubernetes-plugin/blob/master/src/main/java/org/csanchez/jenkins/plugins/kubernetes/KubernetesSlave.java#L75

I have tried in the reverse order, disconnect, then deletePod with the same 
result, even adding a sleep() call between both
I'm not sure what am I missing, if I should call something else to close 
the slave connection
