Glassfish加载JavaScript文件非常慢(>1分钟）

Question

我的Glassfish-Web应用程序有一个奇怪的问题。

大多数时候，我的index.jsp站点加载得非常快。但有时（特别是在更新应用程序的新版本之后），我会在GlassFish中得到一堆TimeOutExceptions。

在Chrome developer控制台中，所有JavaScript文件都处于“挂起”状态，但是.jsp和.css文件加载得非常快。大约1分钟后（有时1.5分钟），大多数JavaScript文件处于状态'200'。其中一些仍然处于“失败”状态。重新加载页面后，一切正常。

查看Chrome的截图。挂起状态:http://s30.postimg.org/ngr85kuk1/Pending.png

完成状态:http://s17.postimg.org/dvdgxmppr/Done.png

这些错误出现在GlassFish上：

我将所有JavaScript文件合并到一个大文件中（并将其缩小），之后，问题就再也没有发生过。
