Zoltan Kiss opened SPR-13212 and commented

Previously the module class supporting Java 8's java.time package was com.fasterxml.jackson.datatype.jsr310.JSR310Module. Now it has been changed to com.fasterxml.jackson.datatype.jsr310.JavaTimeModule.

This is because of a change in the way ZonedDateTime s are serialized; until 2.6 the zone id was included in the string representation. With 2.6 this behaviour has been changed to adhere to ISO 8601 standards in string representation of dates and a new serialization feature WRITE_DATES_WITH_ZONE_ID has been added to enable the old behaviour.

In an effort to provide a backwards compatible behaviour, a new module class JavaTimeModule was created which respects the new serialization feature and the old one was kept which ignores it.

Affects: 4.2 RC2

As of 4.2, we're registering JavaTimeModule if present, just falling back to JSR310Module for compatibility with older Jackson versions.
