Quota error message is not correct from Neutron Liberty

It should be
HTTP/1.1 409 Conflict
Content-Type: application/json; charset=UTF-8
Content-Length: 109
X-Openstack-Request-Id: req-16160ee8-8a26-4f36-8460-348e2355a909

{"NeutronError": {"message": "Quota exceeded for resources: ['network']", "type": "OverQuota", "detail": ""}}%

But it is:
