>             Project: Johnzon
>          Issue Type: Improvement
>          Components: Core
>    Affects Versions: 1.2.0, 1.2.1
>            Reporter: Markus Karg
>            Priority: Major
>          Time Spent: 20m

> Even in these days of modern Java, reducing memory consumption, GC stress and memory
fragmentation, are beneficial side aspects.
> If makes no sense to create new *empty* instances of JsonArray and JsonObject again
and again. For this case, JSON-P provides special *constants*.
> It makes sense to return these constants always.
