Cannot send process cloud event with OffsetDateTime fields

Describe the bug Since 1.12.0.Final my process that’s using an object with OffsetDateTime fields as process variable fails to generate kafka cloud event, representing new task creation.

Expected behavior Process should generate new task and send proper cloud event to kafka topic.

Actual behavior There’s an exception thrown: Error while publishing event to topic kogito-processinstances-events for event org.kie.kogito.services.event.ProcessInstanceDataEvent@62564738: com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Java 8 date/time type java.time.OffsetDateTime not supported by default: add Module "com.fasterxml.jackson.datatype:jackson-datatype-jsr310" to enable handling (through reference chain: org.kie.kogito.services.event.ProcessInstanceDataEvent["data"]->org.kie.kogito.services.event.impl.ProcessInstanceEventBody["variables"]->java.util.Collections$UnmodifiableMap["executionDates"]->com.orange.swing.microservices.process.TaskDates["startDate"])

Adding jackson-datatype-jsr310 nor quarkus-jackson doesn’t help. Problem doesn’t exist in 1.11.3.Final.

To Reproduce

Link to a small reproducer (preferably a Maven project if the issue is not Gradle-specific). https://github.com/jgrabowski/quarkus-bugs

Or attach an archive containing the reproducer to the issue.

Steps to reproduce the behavior:

1. launch kafka on 9092 port (e.g. docker run --rm -p 2181:2181 -p 9092:9092 -e ADVERTISED_HOST=172.17.0.1 -e NUM_PARTITIONS=1 --name kafka johnnypark/kafka-zookeeper)
2. mvn clean compile quarkus:dev
3. curl -X POST "http://localhost:8082/DateProblem" -H "accept: */*" -H "Content-Type: application/json" -d "{\"testDate\":\"2021-03-04T16:55:46.453Z\"}"

Configuration In attached project

Environment (please complete the following information): OpenJDK Runtime Environment (build 11.0.10+9-Ubuntu-0ubuntu1.20.04)

The problem you have is that Jackson started to not register additional modules automatically in Jackson 2.12. So modules need to be registered explicitly.

I’ve tried to register JavaTimeModule via ObjectMapperCustomizer but it doesn’t seem to work.
