如果代理设置不正确，Install4j静默更新程序进程将挂起

Question

如果install4j配置了一个不再存在的“代理脚本”，则似乎会挂起install4j静默更新检查过程。例如:当它被设置为http://127.0.0.1:50000/proxy.pac时，IE会给出一个“连接拒绝错误”，但是在尝试下载脚本时，install4j将不确定地等待。

这也阻止了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之后启动。

安装程序和更新程序在Install4j 6.1.2中创建。在6.1.3的更改日志中，我没有看到任何可以解决这个问题的地方。你能看看我们周围的工作吗？

Answer 1

bug在JRE类中，所以我们不能直接修复它。唯一的选择是传递VM参数。

-Dinstall4j.noProxyAutoDetect=true

这样，代理自动检测就会关闭。
