Java org.hibernate.event.def.EventCache不支持空实体意味着什么？

我在尝试保存实体时出错。我只有在启动服务器时才会出现此错误，而不是在使用dbunit运行单元测试时

我正在努力挽救一个协会。我的单元测试应该与手动测试时遇到的条件完全相同。我在关系的一端添加了一个新实体，以前没有关系

我在单元测试中使用HSQLDB，web应用程序使用SQL Server

我所做的调查并没有结果。对这一信息的解释将证明是非常有用的

下面是测试用例（工作正常！）：

这是服务（注意：我目前正在执行删除/保存操作，条件是已经存在关联-这应该是一对一的，但是是遗留的）：

堆栈跟踪指向上面突出显示的行：

mobilecolorswatchmapuserdefinedDAO.store（相关的\u swatchmap）

堆栈跟踪是：

我有过类似的经验，表定义了一个
可空的
列，但域类将其标记为
不可空的
。试图用
空值保存对象，并且确实保存了该对象，但由于该错误而失败。希望这能有所帮助。
我会添加代码，但由于我甚至不确定异常可能意味着什么，我也不确定应该包含哪些代码。您可以先发布与stacktrace错误相关的代码：）听起来很奇怪，但这也是我们的问题。注释表示nullable=false，而db模式具有allow nulls。我们的数据有一个空值，不知何故验证没有捕获到它。修复注释或修复数据修复了问题。
