This probably relates to #124.
I cannot deserialize OffsetDateTime.MIN and OffsetDateTime.MAX.
With jackson-databind and jackson-datatype-jsr310 (both 2.10.3) on my class path the following works:
ObjectMapper o = new ObjectMapper();
o.findAndRegisterModules();
o.readValue("\"" + OffsetDateTime.now().toString() + "\"", OffsetDateTime.class);
The following does not work:
// (OffsetDateTime.MIN is -999999999-01-01T00:00+18:00)
o.readValue("\"" + OffsetDateTime.MIN.toString() + "\"", OffsetDateTime.class);
// Or:
// (OffsetDateTime.MAX is +999999999-12-31T23:59:59.999999999-18:00)
o.readValue("\"" + OffsetDateTime.MAX.toString() + "\"", OffsetDateTime.class);
Removing the offset or shifting the time by the respective amount of hours seems to work again:
o.readValue("\"-999999999-01-01T00:00+18:00\"", OffsetDateTime.class); // doesn't work
o.readValue("\"-999999999-01-01T18:00+18:00\"", OffsetDateTime.class); // works
o.readValue("\"-999999999-01-01T00:00+00\"", OffsetDateTime.class); // works
