I have an applet that worked fine a month ago but now hangs at startup. It locks up any browser so the process must be killed. It is only this single applet that is causing problems.
我有一个一个月前工作良好的小应用程序，但现在开始运行。它会锁定任何浏览器，因此进程必须被杀死。只是这个单一的applet导致了问题。
The console log shows the jnlp file loading and reloading. Not sure if that is a problem. No exceptions are thrown. I never reach the security check. Near the bottom is this:
控制台日志显示了jnlp文件的加载和重新加载。不确定这是不是一个问题。没有异常被抛出。我从来没有拿到过安检。在底部附近是这样的:
basic: Relaunch because: [currently running JRE doesn't satisfy (version/args)]
This is the bottom part of the console log.
这是控制台日志的底部部分。

The answer is that as of Java 7_21, you can no longer use self signed applets with JNLP. Our work around, for development, is to call the applet not using JNLP.
答案是，在Java 7_21中，您不能使用JNLP来使用自签名applet。对于开发，我们的工作是调用applet，而不是使用JNLP。

You specified -Xss=256K in your java-vm-args when you should have specified -Xss256K (no equals sign).
当您需要指定-Xss256K(不等于符号)时，在java-vm-args中指定-Xss=256K。
