ObjectBox create object entity with map and custom types

Question

How can I support object like that with ObjectBox lib:

@Entity
public class A implements Serializable {
    private Map<String, Integer> aMap;
}

I'm not sure if should I use objectBox converter?
I found some threads which mention that ObjectBox have an open issues with Lists.

Yes, you would need to use a custom type with a converter for this. Which threads do you refer to with List issues?

I would like to understand how can i save a full map in one insert. Can you add a sample with converter and annotation? – motis10 Oct 09 '17 at 13:57
Please start from the [docs on custom types](http://objectbox.io/documentation/custom-types/). – Markus Junginger Oct 10 '17 at 15:02
But i see in the docs that: "At the moment it is not possible to use an array with converters". So what i missed? can you add an example of a map? – motis10 Oct 16 '17 at 06:50
Can you translate the map into some sort of string or serialized format? – Markus Junginger Oct 16 '17 at 09:27
I prefer not to. but its an option. – motis10 Oct 17 '17 at 11:33
You need to do this if you do not want to reconsider the map in favor of another object. – Markus Junginger Oct 20 '17 at 08:58
