我有带有简单的非 JPA Hibernate 基于域和 dao 子模块和 web 子模块的 EAR。我想使用 JTA 和容器管理事务。在 WildFly 9（使用 Hibernate4）上部署时，一切正常。我将应用程序迁移到 WildFly 10（使用 Hibernate5），但在浏览器中单击几次后抛出异常：
编辑：添加了完整的堆栈跟踪：

我在 github 上创建了简单的复制器，请参阅https://github.com/trepel/primrose-hibernate-simple
拜托，如果您知道可能出了什么问题，请告诉我。
编辑：我进一步简化了复制器，现在它只是简单的基于 Spring 的 Web 应用程序（战争档案），请参阅https://github.com/trepel/wildfly-hibernate5-error
非常感谢您的提示。
