As of Jackson 2.6 the module class supporting the java.time (java8) package has changed [SPR-13212]

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.

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