jackson 2.x still supports java 7 and thus does not automatically support java 8 classes. this will change with jackson 3.x (see e.g. this [PR adding JSR310 date support] to 3.x). PR #251 added documentation on how a custom `ObjectMapper` can be registered - but there's no reason why we can't just enable auto-detection centrally. the docs mention that performance should be considered, but this is IMHO not relevant here since we only construct it once and then keep the same `ObjectMapper` (which in turn the docs mention as best practices).
