RFC 8259 support

[Michael Scalia]

I'm having trouble finding which version of Jackson supports which JSON RFC. 

Which 2.x version of Jackson supports RFC 8259?

Thanks,

Michael Scalia

What is RFC 8259, and why do you care?

RFC 8259 is The JavaScript Object Notation (JSON) Data Interchange Format. It obsoletes RFC 7159, which in turn obsoletes RFC 4627. I believe 4627 was the original JSON specification.

I care because my server uses Jackson to parse and generate JSON. Some customers have asked about support for the more recent JSON RFCs. In particular, I've been asked about this change from https://tools.ietf.org/html/rfc7159#appendix-A:

   o  Changed the definition of "JSON text" so that it can be any JSON
      value, removing the constraint that it be an object or array.

Thanks,

Ah. That makes sense, thank you for clarification.

I am not aware of any deviations; at least no bug reports exist. My recollection is that newer json(-related) specification do not contain major changes.

Now, with respect to that particular change, yes, Jackson does support reading of any JSON root-level value out of the box.

Same is true for things like "line-delimited JSON" (https://en.wikipedia.org/wiki/JSON_streaming -- line-delimited and concatenated JSON).
