+msgstr "每次部署时，JBoss 都会为每个顶层部署创建一个新的类加载器，例如为 EAR 文件。你也得记住应用服务器里的类不仅由类名也由自己的类加载器定义。所以，假设缓存没有作为部署的一部分部署，你也可以部署应用程序并把属于这个部署的类的实例放入缓存。如果你进行重部署并试图进行前面所放入的数据的 get 操作，就会导致 ClassCastException 异常。这是因为即使类名相同，类定义也会不同。当前的类加载器和最开始放入类时的不同。"

+msgstr "通过启用 marshalling，你可以控制缓存中数据的生命周期，在卸载时，你取消激活 region 并取消部署时注册的类加载器，你将在本地剔除缓存里的数据。这意味着在下一次部署时，数据不会在缓存里，因此避开这个问题。很明显，使用 marshalling 来绕开这个问题只适用于你具有某种持久化数据的支持（如使用类加载器），或在持久性框架里把 JBossCache 当作二级缓存的时候。"
