已签名的JNLP小程序在加载时卡住

javajnlpsigned-applet
3

我有一个小程序，一个月前还很好用，但现在在启动时卡住了。这会锁定任何浏览器，所以必须停止该进程。只有这个小程序出现问题。

控制台日志显示jnlp文件正在加载和重新加载。不确定这是否是问题。没有抛出异常。我从未到达安全检查点。最后出现以下内容：

 basic: Relaunch because: [currently running JRE doesn't satisfy (version/args)]

这是控制台日志的底部部分。

尝试按照Oracle的Java SE 7桌面技术故障排除指南操作，看看是否有助于诊断您的问题。从描述来看，可能是Java 7u21与您的应用程序不兼容，并且将Java系统更新到Java 7u21导致了您的问题。 - jewelsea
我相信这是真的。我们将在不久的将来更新到非自签名小程序。在开发中，我相信我们可以通过不调用JNLP来启动来解决这个问题。 - jebrick
你解决了这个问题吗？ - jsosnowski

截至Java 7_21版本，您不能再使用自签名的applet与JNLP一起使用。我们的解决方法是在开发时不使用JNLP来调用applet。

您不能再使用JNLP自签名小程序。我认为这是不正确的，并通过测试我自己的自签名应用程序进行确认 - 只要用户在出现可怕的对话框时单击“确定”按钮，它就可以正常工作。有关更多信息，请参见详细介绍Java 7 Update 21安全改进。 - Andrew Thompson

在你的java-vm-args中，你指定了-Xss=256K，但是正确的应该是指定-Xss256K（没有等号）。
