Install4j 静默更新程序进程在代理设置不正确的情况下挂起

Question

如果 Windows 配置的 "proxy script" 不再存在，install4j 静默更新检查过程似乎会挂起。例如：当它设置为 http://127.0.0.1:50000/proxy.pac 时，IE 给出 "connection refused error"，但 install4j 将在尝试下载脚本时无限期地等待。

这也会阻止我们自己的应用程序启动，因为它被配置为在静默更新检查后启动。

安装程序和更新程序是在 Install4j 6.1.2 中创建的。我在 6.1.3 的更改日志中没有看到任何可以解决此问题的内容。您能看看或为我们提供解决方法吗？

该错误存在于 JRE 类中，因此我们无法直接修复它。唯一的选择是传递 VM 参数

-Dinstall4j.noProxyAutoDetect=true

安装程序关闭代理自动检测。
