Sorry, the JSON missing in "step 1" is inline in "step 3".

Also, null values outside of arrays also fail to parse due to a Precondition
failure:

I'm pretty sure null is a valid JSON type, but even if it's not, then this
should
throw a ParseError.

null is a valid JSON type as per JSON spec
(http://tools.ietf.org/id/draft-crockford-jsonorg-json-04.txt). I just wrote a
test
(thanks for providing a good example) and this is indeed failing. We will fix
this
and put it in our next release.

Actually, well designed Json should just omit the field instead of passing
nulls.
However, Gson should handle the case as well, and that is why we have now added
support for it.
