使用 1.6.4.1 SDK，当我运行 appcfg.sh 时，我得到“5% 扫描 jsp 文件”，然后它永远旋转（我让它在一夜之间运行），消耗了我的一个 CPU 的 100%。起初，我怀疑它与编译 JSP 问题相同，但我什至没有做到这一点。它看起来像是 AbstractGlob 和/或 javax.util.Regex 中的某种错误。该项目在这里，以防您想自己复制它。
其他人有这种经验吗？知道可能是什么原因造成的吗？有什么办法可以绕过它，以便我可以上传我的应用程序？
这是来自 kill -QUIT 的堆栈跟踪：

当我将 WebXml 映射更改为security-constraintfrom /**to/*时，问题就解决了。我的理解是这个新的安全约束设置会匹配/foo但不匹配/foo/bar：对吗？如果是这样，那么我可能有办法绕过这个错误。但它看起来像一个非常讨厌的错误AbstractGlob，无论人们在哪里都可以找到该代码......
