ExtensionsV1beta1Api.createNamespacedIngress is throwing error for servicePort

[jeesmon]

java-client: v1.0.0-beta1
k8s: v1.8.2

In V1beta1IngressBackend model, servicePort is String. But calling ExtensionsV1beta1Api.createNamespacedIngress with "servicePort": "443" throws

{"kind":"Status","apiVersion":"v1","metadata":{},"status":"Failure","message":"Ingress.extensions \"ingress\" is invalid: [spec.backend.servicePort: Invalid value: \"443\": must contain at least one letter or number (a-z, 0-9), spec.rules[0].http.backend.servicePort: Invalid value: \"443\": must contain at least one letter or number (a-z, 0-9)]","reason":"Invalid","details":{"name":"ingress","group":"extensions","kind":"Ingress","causes":[{"reason":"FieldValueInvalid","message":"Invalid value: \"443\": must contain at least one letter or number (a-z, 0-9)","field":"spec.backend.servicePort"},{"reason":"FieldValueInvalid","message":"Invalid value: \"443\": must contain at least one letter or number (a-z, 0-9)","field":"spec.rules[0].http.backend.servicePort"}]},"code":422}

            }
        ]
    }
}

kubectl apply -f ingress.json 
The Ingress "ingress" is invalid: 
* spec.backend.servicePort: Invalid value: "443": must contain at least one letter or number (a-z, 0-9)
* spec.rules[0].http.backend.servicePort: Invalid value: "443": must contain at least one letter or number (a-z, 0-9)

If I change "servicePort": "443" to "servicePort": 443 and run kubectl apply -f ingress.json, Ingress is created. But there is no way to do that using the V1beta1Ingress model for java client.

Duplicate of #115 IntOrString isn't handled properly.

We need to regenerate the client...
