Hibernate-reactive: 使用 Quarkus 更新关联实体失败并显示 UnsupportedOperationException

嗨，我们面临的问题是在尝试更新关联实体时遇到java.lang.UnsupportedOperationException 。 我们在 Quarkus 中使用 hibernate-reactive。 我知道有一个问题 #506 应该可以解决这个问题，但它似乎对我们不起作用。

当调用CampaignDao#update方法，而无需实例Schedule与相关联的Campaign的Schedule实例获取存储按预期方式。 在Schedule实例与Campaign关联并持久化之后调用该方法后发生异常。

我正在创建这个问题，因为我在您的examples文件夹中找不到示例实现。 也许您还可以包含一个关于如何更新关联实体的内容。
