java - 已签名的 JNLP applet 卡在负载上

Question

我有一个小程序在一个月前运行良好，但现在在启动时挂起。它会锁定任何浏览器，因此必须终止该进程。只有这个小程序导致了问题。

控制台日志显示 jnlp 文件加载和重新加载。不确定这是否是一个问题。没有异常被抛出。我从来没有到达安全检查。靠近底部是这样的:

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

这是控制台日志的底部。

Answer 1

答案是，从 Java 7_21 开始，您不能再将自签名小程序与 JNLP 一起使用。为了开发，我们的工作是调用不使用 JNLP 的小程序。
