界: Time and State
分布式计算是关于时间和状态的。也就是说，为了让多个组件相互通信，必须共享状态，所有这些都需要时间。
大多数程序员都会将其工作拟人化。他们会让一个控制线程以同样的方式（他们必须自己完成工作时采取的方式）执行整个程序。然而，现代计算机不同任务之间切换得非常快，在多核、多 CPU 或分布式系统中，两个事件可能完全同时发生。程序员预期的程序执行过程与实际情况之间存在差距，即存在缺陷。这些缺陷与线程、流程、时间和信息之间的意外交互有关。这些交互是通过共享状态发生的：信号量、变量、文件系统，以及总而言之，可以存储信息的任何内容。
J2EE Bad Practices: Insufficient Session Expiration
Abstract
该方法设置了一个永远都不会过期的会话。
Explanation
会话持续时间越长，攻击者危害用户帐户的机会就越大。当会话处于活动状态时，攻击者可能会强力攻击用户的密码、破解用户的无线加密密钥或者通过打开的浏览器强占会话。如果创建大量的会话，较长的会话超时时间还会阻止系统释放内存，并最终导致 denial of service。
例 1： 以下示例中的代码为实现最长不活动时间间隔而设置了负值，以使会话保持无限期的活动状态。

HttpSession sesssion = request.getSession(true);
