ExtensionsV1beta1Api.patchNamespacedDeployment throws 500 Internal server error because of wrong content type in header

[karthikkondapally]

reason: content-type in header is being set to application/json-patch+json instead of application/strategic-merge-patch+json
this is causing 500 internal server error

when i test the patch call to /apis/extensions/v1beta1/namespaces/default/deployments/kubeexample?pretty=false with content type as application/json-patch+json (in postman rest client) , getting following error

{
    "kind": "Status",
    "apiVersion": "v1",
    "metadata": {},
    "status": "Failure",
    "message": "json: cannot unmarshal object into Go value of type jsonpatch.Patch",
    "code": 500
}

I believe content type should be application/strategic-merge-patch+json (with it as content type deployment gets updated)

in ExtensionsV1beta1Api.patchNamespacedDeploymentCall

localVarContentTypes is being set to application/json-patch+json instead of application/strategic-merge-patch+json because of ApiClient.selectHeaderContentType(String [] arr) always select first element of array({"application/json-patch+json", "application/merge-patch+json", "application/strategic-merge-patch+json"}) as it matches with regex.

Same error when calling new NetworkingV1Api().patchNamespacedNetworkPolicy()

Any word on this issue?

@mjschmidt
with strategic merge patches, it throws internal server error(because of SWAGGER/OPENAPI/codegen related issues). but with Json Patches it will work.
working example of JsonPatch is here https://github.com/kubernetes-client/java/blob/master/examples/src/main/java/io/kubernetes/client/examples/PatchExample.java

How can we use a JsonPatch to patch a Node?
