最近我在Hibernate中遇到了一个相当“怪异”（缺乏更好的词）的问题。当试图坚持我的实体时，会抛出以下WARN / ERROR：
WARN [quartzScheduler_Worker-2] LoadContexts:122 - HHH000100: Fail-safe cleanup (collections) : org.hibernate.engine.loading.internal.CollectionLoadContext@4bf3ab85<rs=oracle.jdbc.driver.OracleResultSetImpl@1786369e>

说实话，我对错误感到困惑。这是一个相当庞大的应用程序，我不知道这样的错误是如何发挥作用的。我的猜测是Hibernate在某种程度上感觉需要触发Collection清理，并且这会在以后尝试持久化实体时导致问题。然而，故障安全清理警告应该是一个错误，在Hibernate 3.2.5中修复（参见https://hibernate.atlassian.net/browse/HHH-2936）。我的项目中使用的Hibernate版本是4.2.7，因此不应该是问题。到目前为止，我在这个问题上找不到很少的信息，因此我的问题。 你们有什么建议在我的代码中寻找什么可能最终触发这个？
非常感谢！
