Hi John
Yes, that's a problem.
Even in the Sling "open source space", many examples/code excerpts include references to proprietary Adobe code, not
available to "pure" Sling projects...

Hi Juerg,
I am using Apache sling as part of AEM. Adobe packages its own very similar
class com.day.cq.commons.TidyJsonItemWriter. Of course that doesn't help if you
aren't using AEM.

Thanks Daniel, John,
As the app makes high usage of dynamic JCR Node features (based on
nt:unstructured, mixins, etc), a relatively static sling model class
seems a bit unpractical, though a typesafe contract would be desirable,
of course.
On the other hand, the JsonItemWriter would almost be ideal but is not
present in Sling 11 anymore. Actually, the entire commons.json package
disappeared. Seemingly, this package has been replaced by Apache Johnzon
but I cannot find anything equivalent to JsonItemWriter.
Anybody aware of its substitute?
Thanks,
Juerg
