> Polymorphism attributes not serialized if @JsonbTypeInfo is not attached to

> -----------------------------------------------------------------------------------------

> Key: JOHNZON-402
> URL: https://issues.apache.org/jira/browse/JOHNZON-402
> Project: Johnzon
> Issue Type: New Feature
> Components: JSON-B
> Affects Versions: 2.0.0
> Reporter: Markus Jung
> Assignee: Markus Jung
> Priority: Minor
> Fix For: 2.0.1

> Time Spent: 20m
> Remaining Estimate: 0h

> After thinking through the polymorphism code again for JONZON-401 I noticed
> an issue where polymorphism properties aren't taken into account if the
> @JsonbTypeInfo annotation is not attached to a direct parent of the
> serialized class.
> Take this example test:
> {code:java}
> public class JsonbMultiLevelPolymorphismTest {
> @Rule
> public JsonbRule jsonb = new JsonbRule();
> @Test
> public void test() {
> ConcreteSomething info = new ConcreteSomething();
> assertEquals("{\"@type\":\"concrete\"}", jsonb.toJson(info));
> }
> @JsonbTypeInfo(
> @JsonbSubtype(alias = "concrete", type = ConcreteSomething.class)
> )
> public static abstract class AbstractTopLevelSomething { }
> public static abstract class AbstractMiddleLevelSomething extends
> AbstractTopLevelSomething { }
> public static class ConcreteSomething extends
> AbstractMiddleLevelSomething { }
> } {code}
> Test result:
> {code:java}
> org.junit.ComparisonFailure:
> Expected :{"@type":"concrete"}
> Actual :{} {code}
>
> The spec doesn't mention that @JsonbTypeInfo has to be attached to a direct
> parent. This also works perfectly fine in yasson, so I see no reason why it
> should not in johnzon.
