Justin Edelson resolved SLING-6295.
-----------------------------------
    Resolution: Fixed

Fixed in r1770102.

The actual code used for JSON output could not be reused from Sling Commons JSON but was adapted for use with the Jackson API.

> When a model class has a property of type Resource (or a collection of Resource objects), attempting to serialize that class into a String produces a StackOverflow due to the getParent() method.
> The simplest solution would be to use Jackson mixins to skip the getParent() (and, for good measure, the getResourceResolver() and getResourceMetadata()) methods. A better solution would be to simply use the standard Sling JSON in these cases.
