java - 在Eclipse中运行Tomcat并获取“来自持久存储的异常加载会话”

我使用Eclipse Kepler开发基于Sprig / Hibernate / PostgreSQL的应用程序。该应用程序在由Eclipse管理的Tomcat中运行。这通常很好。

修改并保存任何jsp约10次后，我得到以下异常：

唯一的解决方案是停止Tomcat，执行Project->Clean，然后重启Tomcat。当然会话丢失了，我必须再次登录应用程序。

这个问题严重影响了我的开发工作流程，到目前为止我还没有找到解决方案。

怀疑文件系统问题，我尝试在tmpfs中创建一个文件夹并将其用作Tomcat的服务器路径（在Eclipse中设置），但它没有改变任何内容。

请注意，这只发生在我的笔记本电脑上（Kubuntu 13.10）一位同事拥有相同操作系统的同一台笔记本电脑，但没有看到问题。

似乎问题是会话在文件系统上被破坏而Tomcat会对此产生阻塞。为什么会这样？
