Java Optaplanner分数损坏

我正在研究一个类似于车辆路径问题的问题，我有一个避免多个员工同时使用同一辆车的规则。另外，我使用多级可弯曲分数只是为了计算详细的分数。 按照这条规则 我已启用FAST_ASSERT，因此产生以下例外情况：

java.lang.IllegalStateException: Impossible VariableListener corruption: the expectedWorkingScore
(-788init/[0/0/-10/-20/-3/0/-12/-788/0/0]hard/[0/0/-25/-75/0]soft) is not the workingScore 
(-788init/[0/0/-10/-60/-3/0/-12/-788/0/0]hard/[0/0/-25/-75/0]soft) after all VariableListeners were triggered without changes to the genuine variables.
But all the shadow variable values are still the same, so this is impossible.

在AbstractScoreDirector中，我查看了move类型，它是ChainedChangeMove，它是toString，如下所示：

T:1568135-2-10- {T:1656844-2-10- -> T:1656844-2-10-}

这让我感到惊讶，因为它试图将相同的链分配给实体，就像以前一样（1656844是链中的第一个实体）

A.需要帮助理解上述异常，以便我能够修复它。
B.我们如何确保移动创建者不会创建无用的移动，即将相同的事实分配给实体，就像上面一样

更新的完整断言异常：

您可能不相信，但FAST_ASSERT不会抛出任何损坏异常。我知道这只是巧合，但我已经试过多次了。但我会跟踪日志并更新我的问题。我几乎遇到了同样的问题。我已经从FAST_ASSERT切换到FULL_ASSERT，然后错误消息指出变量侦听器的问题正在破坏工作解决方案。我已经删除了侦听器逻辑并将其移动到我的域逻辑，错误不再发生。您可能不相信这一点，但FAST_ASSERT不会引发任何损坏异常。我知道这只是巧合，但我已经试过多次了。但我会跟踪日志并更新我的问题。我几乎遇到了同样的问题。我已经从FAST_ASSERT切换到FULL_ASSERT，然后错误消息指出变量侦听器的问题正在破坏工作解决方案。我已经删除了侦听器逻辑，并将其移动到我的域逻辑中，错误不再发生。
