Review comment:
It seems like that the most adequate JsonProcessingException is
JsonParseException that could apply here. Another possibility is to change the
exception in return type to something like IOException and throw that here but
it seems it's more vague than throwing JsonParseException.
Another option is to simple throw IllegalArgumentException here instead of
Left. That would correspond to the `readTree(InputStream)` as well. What do you
think?
