> The JsonSerialization<> load code doesn't work on gcs as it uses
> "stream.available()" to fail with a meaningful message if the stream is empty.
> But that method is meant to say how much data is available without blocking,
> something we actually get wrong ourselves. Google GCS team didn't get it
> wrong, so on a read(), if there's no local buffer, an EOFException is raised
