REST API 负载中的 thorntail 和多态性部署问题

Question

我必须将 Wildfly Swarm (2018) 上的现有应用程序运行迁移到 Thorntail。是的，我知道这已经过时了，但是...... 我用另一个应用程序做到了，没有问题。但现在我收到部署错误：

开机调试代码，发现解析Endpoint的注解有NPE。与我的其他应用程序的不同之处在于，有效负载使用多态性：

@JsonTypeInfo(use = JsonTypeInfo.Id.NAME, include = JsonTypeInfo.As.EXTERNAL_PROPERTY, property = "eventType")
    @JsonSubTypes({
            @JsonSubTypes.Type(value = PayloadDocument.class, name = "document"),
            @JsonSubTypes.Type(value = PayloadCampaign.class, name = "campaign"),
            @JsonSubTypes.Type(value = PayloadMessage.class, name = "message")
    })
    public void setPayload(Payload payload) {
        this.payload = payload;
    }

class 负载是抽象的。

我解决了这个问题，没有切换到 Quarkus（下一步我肯定会做的）。问题是，我在 Payload PoJo 中使用了可选属性。我通过在调试器中更深入地挖掘发现了它。删除 Optional 属性后，部署按预期工作。
