RangeSet deserializer fails for content nulls with NPE #142
Description
(from https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=65197)
Looks like RangeSet deserialization fails with non-Jackson exception (NPE?).
We should instead fail with a DatabindException.
In future we may want to offer configurability for different behavior (automatic skipping, f.ex), and/or see that existing @JsonSetter configurability (annotation, config overrides) mechanisms work to avoid this issue.
