I'm using kubernetes-client version 2.0.0, with kubernetes server version

Server Version: version.Info{Major:"1", Minor:"9", GitVersion:"v1.9.5", GitCommit:"f01a2bf98249a4db383560443a59bed0c13575df", GitTreeState:"clean", BuildDate:"2018-03-19T15:50:45Z", GoVersion:"go1.9.3", Compiler:"gc", Platform:"linux/amd64"}

I think the issue is with
"status":{"phase":"Terminating"}}, the parser expects something like "status":"Terminating"

this is a known issue in this jar. #86
see #86 (comment)
This error will arise for all delete K8 objects.
