无法找到或服务资源

我正在 Glassfish 4 服务器上使用 Java EE 6 和 Primefaces 制作一个 Web 应用程序。我越来越频繁地遇到同样烦人的错误。我尝试用谷歌搜索这个问题，但还没有找到有效的解决方案。有时，应用程序执行时完全没有问题，但突然之间，同样的错误会一遍又一遍地发生。这是我的堆栈跟踪：

同样的错误会发生几次，但随后无法提供资源，例如：jquery/jquery-plugins.js、layout/layout.js、jquery/jquery.js、primefaces.js。全部来自 Primefaces 库。

这个错误已经困扰我很长一段时间了，非常感谢您的回答！

这很可能是 grizzly 框架的错误。

可能导致bug： https://java.net/jira/browse/GLASSFISH-20681?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

在那个 Jira 中，有一个jar修补。复制到modules目录，清除 OSGI 缓存（删除 glassfish4\glassfish\domains\domain1\osgi-cache）并重新启动。这对我有用。

另请参阅：当返回多个大响应时，Servlet 中抛出 GF4 不正确的超时异常（请求）
