Review Comment:
I think this is fine and a good way to test it. Java doesn't support
unsigned int, so if you're forced to convert to signed, this is the best way.
The underlying 32-bit machine representation will almost certainly be the same.
(I say "almost" baring whatever little/big endian weirdness -- but even then
the conversion to/from Protobuf should be consistent.) So I think we're good.
