java.lang.RuntimeException: ERROR: Failed to recover corrupt cache entry
提问by paul
I just had this error message from one of my users. (IE8, Java 1.6.20 ). It is from an applet which receives instructions from Javascript and executes certain processes on the client.
我刚刚从我的一位用户那里收到了这条错误消息。（IE8，Java 1.6.20）。它来自一个从 Javascript 接收指令并在客户端执行某些进程的小程序。

Any iddeas what could be causing this?
任何想法可能导致这种情况？

It might be this bug. If so the workaround would appear to be to clear the java cacheand try again.
可能是这个错误。如果是这样，解决方法似乎是清除 Java 缓存并重试。

I have experienced this problem at java1.8_0.31 and Only workaround I found so far that put packed jars (pack.gz) to same directory with your jar(s). When tracing the servlet i see that
我在 java1.8_0.31 遇到过这个问题，到目前为止我发现的唯一解决方法是将打包的 jars (pack.gz) 与您的 jar(s) 放在同一目录中。在跟踪 servlet 时，我看到

Client behaves coming plain jar file as packed and gziped jar. Maybe need to examine HTTP Header to why client do that.
客户端将即将到来的普通 jar 文件视为打包和 gzip 的 jar。也许需要检查 HTTP Header 以了解为什么客户端会这样做。
