    Description

      Now that Jackson 2.10 is used, we need to enable polymorphic type validators by default (to deal with the case of Default Typing being enabled through `@JsonTypeInfo` annotated classes).
      To do that we most likely need to:
      1) create a custom extension of `BasicPolymorphicTypeValidator` that register a white-list of FQCNs obtained through a system property (or through MP Config if available)
      2) set such validator in the ObjectMapper instances we create in the resteasy providers (`mapper.setPolymorphicTypeValidator(...)`)
      3) create a testcase verifying this
      4) provide additional documentation (about the property for white-list specification)
