Support WildFly

As an alternative to Payara or default runtime.

WildFly/Hibernate is ok in my fork, I have not tried to run it in OpenLiberty.

Does it also work with Payara? How about the Arquillian tests? If so, let me create a separate branch and you can issue the PR there. Once I can examine the code and do regression testing to verify everything is OK for both servers, we can merge it to master.

Yes, I added Github Actions to build it and running tests. https://github.com/hantsy/cargotracker/

1. JPA Entities, there are small fixes added due to some Hibernate-specific issues. Check notes in https://github.com/hantsy/cargotracker/blob/master/src/main/java/org/eclipse/cargotracker/domain/model/cargo/Itinerary.java
2. Jackson is used by default in the latest WildFly, but not configure Java 8 DateTimeSupport. https://github.com/hantsy/cargotracker/blob/master/src/main/java-wildfly/org/eclipse/cargotracker/infrastructure/routing/client/JacksonObjectMapperContextResolver.java
3. To avoid the famous lazy init exception from Hibernate etc, use a transaction to wrap the codes where some lazy access on a proxied object there, I added some @transactional in some web layer codes, and use manual UserTransaction in the tests to make the codes work. https://github.com/hantsy/cargotracker/blob/master/src/test/java/org/eclipse/cargotracker/application/BookingServiceTest.java It seems the @Transactional did not work in Arquillian tests directly.

Another issue I found about the LocalDateTime persistence in Hibernate, https://github.com/hantsy/cargotracker/blob/master/src/main/java/org/eclipse/cargotracker/domain/model/cargo/Leg.java#L66, the nano value is different when fetching from db.

Not sure there are some configuration in Hibernate to fix it.

I just want to be clear - at this point do you have a codebase that works with both Payara and WildFly? Or is it the case that you have ported the code to WildFly and it no longer works with Payara? If it’s the latter, do you need help achieving the former?
