jx.GetEncoder() is called in the oas_response_encoders_gen.go, but jx.PutEncoder() is not called, is this a bug?

[davidxifeng]

w.Header().Set("Content-Type", "application/json")
w.WriteHeader(200)
span.SetStatus(codes.Ok, http.StatusText(200))

e := jx.GetEncoder()
e.ArrStart()
for _, elem := range response {
 elem.Encode(e)
}
e.ArrEnd()
if _, err := e.WriteTo(w); err != nil {
 return errors.Wrap(err, "write")
}
return nil

it seems that it will always get from the pool, but never return to the pool
