Minor Upgrade Jackson to 2.12.0.
This upgrade includes ticket #2683 (Explicitly fail (de)serialization of java.time.* types in absence of registered custom (de)serializers) which now requires explicit registration in the ObjectMapper of the required modules:
new ObjectMapper()
must now be written:
new ObjectMapper().findAndRegisterModules()
if serialization of Java 8 time objects is needed, along with the adding in the dependencies of jackson-datatype-jsr310.
