org.hibernate.AssertionFailure：例如无法执行取消删除

当我尝试在一些删除操作后进行读取时，我收到此休眠断言错误。

我找不到任何有关此“无法执行取消删除”错误的信息，除了源代码 https://github.com/hibernate/hibernate-orm/blob/master/hibernate-core/src/main/java/org/hibernate/engine/spi/ActionQueue.java，所以我想，也许我正在做一些明显错误的事情......

堆栈跟踪如下，

AssertionFailure:43 -  - HHH000099: an assertion failure occured (this may indicate a bug in         Hibernate, but is more likely due to unsafe use of the session): org.hibernate.AssertionFailure: Unable     to perform un-delete for instance X

Regards,

我也有同样的问题。发生的情况是，我正在删除相关的bean，我们称它们为A和B。我删除了Bs，然后继续查找链接到As的实体C，并将A类型的bean作为查询的参数，并使查询导致此异常。我最好的猜测是，当我删除 B 时，实体 D 上的级联注释引用 A 和 B，已删除了 As，然后将已在数据库级别删除的实体作为查询参数给出，导致了问题。

重新排列代码，以便我首先删除从 C 到 A 的引用，然后then继续删除 B 和 A 似乎可以解决此问题。
