更新到 Hibernate 5.2.4 后出现 ConcurrentModificationException，Spring 4.3.3，Struts 2.5.5
ConcurrentModificationException after update to Hibernate 5.2.4, Spring 4.3.3 , Struts 2.5.5
我正在升级旧项目的框架。更新涉及几个主要版本：
- 休眠 3.1 -> 5.2.4
- Spring 2.1 -> 4.3.3
- Struts 2.1 -> 2.5.5
- Spring-安全 2.x -> 4.1.3
- Apache Commons Collections 3.2.1 -> 3.2.2（如果需要可以更新到 4.x）
JDK 没有受到任何更新，我们正在使用 Java 8。虽然我相信在更新之前没有使用任何 Java 8 功能的源代码。
我依靠编译器修复了所有 class 引用，更新了框架的 DTD，等等。
最后，该项目编译时只出现了一些弃用问题，没有出现任何错误。但是，一旦我加载索引页面并出现登录提示，我就会收到以下错误。
下面的代码中只有 4 个 class 不是 Spring/Strut/Hibernate 的一部分，但它们所做的只是在 Spring 安全性上调用 doFilter。简单的授权。我不创建、return 或迭代任何列表或哈希图。
欢迎任何想法。下面的完整堆栈跟踪。谢谢。
