Niclas Hedhman commented on ZEST-141:
-------------------------------------

Well, as described this is not possible, since you can not have generics on the annotations and the value must be of some specific types (java.lang.Object is not allowed).

But we can make it into a String type, and use deserialization to any other type if the property is not a String. I think that is a reasonable compromise.

> Define default value where I declare the Property, such as:
> {code}
> public interface ABC {
>    @UseDefaults(value="127.0.0.1")
>    Property<String> hostname();
>    @UseDefaults(value=8080)
>    Property<Integer> port();
> }
> {code}
