javadoc should refer to JSON properties, not JSON keys

Like it or not, we settled on calling these properties in ML8. The javadoc is the last refuge of the old "JSON key" terminology.

We should clean this up, but IMO it can wait until the more general javadoc cleanup/improvement we've previously discussed.

Assigning this to Sam and 8.0-2 for now, but I expect it'll really end up being me and some later 8.0-x milestone.

The nightly build isn't pulling the right branch right now, I think, so I'm not able to verify this thoroughly by conducting a search on pubs. I've sent Sravan a note about the build and will circle back to this when we have a resolution.
