             Summary: Polymorphism attributes not serialized in nested objects
                 Key: JOHNZON-401
                 URL: https://issues.apache.org/jira/browse/JOHNZON-401

See the following test:
{code:java}
package org.apache.johnzon.jsonb.polymorphism;

import jakarta.json.bind.annotation.JsonbSubtype;
import jakarta.json.bind.annotation.JsonbTypeInfo;
import org.apache.johnzon.jsonb.test.JsonbRule;
import org.junit.Rule;
import org.junit.Test;

import static org.junit.Assert.assertEquals;

public class JsonbNestedPolymorphismTest {
    @Rule public JsonbRule jsonb = new JsonbRule();

    @Test
    public void test()
    {
        Wrapper wrapper = new Wrapper();
        wrapper.something = new ConcreteSomething();

        
assertEquals("{\"something\":{\"@type\":\"concrete\",\"value\":\"asdf\"}}", 
jsonb.toJson(wrapper));
    }

    @JsonbTypeInfo({
            @JsonbSubtype(alias = "concrete", type = ConcreteSomething.class)
    })
    public static class AbstractSomething {

    }

    public static class ConcreteSomething extends AbstractSomething {
        public String value = "asdf";
    }

    public static class Wrapper {
        public AbstractSomething something;
