Quarkus hibernate orm and panache throwing JsonBException
This is an example where Quarkus Hibernate ORM and JPA and Quarkus Hibernate ORM with Panache is throwing a JsonbException when an Entity has a Many-One and One-Many relationship with itself.

I have added a Spring Boot application where the recursive reference problem is solved by using @JsonIdentityInfo.
However the same solution is not working for Quarkus.
The reason for the JsonbException is that quarkus-resteasy-jsonb and quarkus-resteasy-jackson are present in the project pom file where it would seem that quarkus-resteasy-jsonb is taken precedence over the other one for serializing/deserializing classes. And jsonb uses Yasson for that which don't know what to do with the @JsonIdentityInfo annotation.
The solution is to delete quarkus-resteasy-jsonb so that quarkus-resteasy-jackson so that Jackson is used instead to serialize/deserialze a class that hasand will process the @JsonIdentityInfo annotation.
