Review Comment:
I created a test in PR #90 in the `johnzon-mapper` module that doesn't use
JSON-B and instead uses `Mapper.readObject`. The handling seems identical and
any RuntimeException thrown from the user's code is wrapped in a
`MappingException`. If there is still a scenario I'm missing, the most helpful
way forward would be if you hack up a small test case I can use as a reference.
