   I think the closing logic on `PredefinedOptions` is not going to work.
   It is an enum and hence a singleton instance. If someone calls close on the enum, the resource from some other call to `createColumnOptions()` will be disposed. That can even lead to seg faults under concurrency.
   
   The root cause is that objects with life cycle and enums do not go together well.
