固定到任务栏时，Java Web Start 遇到 CouldNotLoadArgumentException

Question

想知道是否其他人遇到了这个问题，并且有已知的解决方法。我们的 UI 是通过 java web start 部署的。它运行良好，除非用户将图标固定到 Windows 7 中的任务栏。我们使用的是 JRE 7u7。

jaavws.exe 报告找不到缓存，见下文。请记住，当我们从桌面启动相同的图标时，这非常有效:

Answer 1

报告错误的 URL:http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4774096这只是说他们无法繁殖。

我们发生了同样的错误，用户升级到 Update 34 并没有解决问题，但是重新安装了应用程序并且一切正常。
