Answer 1

你也在使用jre1.6.0_07版本 - 但你的classpath和java_home指向的是……(Need more context to complete the translation)

JAVA_HOME=C:Program FilesJavajdk1.6.0_06in;.; CLASSPATH=C:Program FilesJavajdk1.6.0_06in;.;

这些路径的混合可能会给运行时造成一些问题。

我建议卸载所有版本的Java（似乎您有几个版本），并升级到最新版本。然后确保所有变量都指向单个版本。

Answer 2

你是否在IE 7中运行某些网页应用程序？我看过互联网上发布的几个类似的崩溃情况。如果是这样，请尝试使用其他浏览器。

可能的接受方式可以是，

Try other browser then IE, if you are running some application under IE
Try de-install JRE/JDK, and install a new from the scratch. Choose a released version, not beta. And please don t do it under program files this time, choose a path without spaces. Although, spaces can t be the reason of the crash

这个崩溃不应该再发生了。如果仍然持续发生，请按照错误提示报告。

Answer 3

内部错误应该始终提交给Sun。无论您的代码有多糟糕，这些错误都不应该发生。Sun的提交网页在这里或在这里。

只需确保它尚未报告，并且您可以轻松地重现它。

Answer 4

如果您偶爾或經常遇到這個問題，則可以向sun記錄錯誤。此外，我建議您如果可能的話升級您的JVM版本，因為這是sun首先建議的。
