我试图用argo建立eclipse工程，出现java.lang.IllegalArgumentException: URI is not hierarchical

我希望建立一个eclipse的web工程，在eclipse里运行tomcat,出现一下错误
GroupConventionFactory.java
38: ClassLoader cl = Thread.currentThread().getContextClassLoader();

44: URL url = cl.getResource(".");

url是这样的file:/usr/lib/jvm/java-6-openjdk-common/jre/lib/ext/pulse-java.jar!/

从 Log 上看当前 Thread 的 context class loader 貌似是一个 Extension Class Loader，但是 Thread context class loader 默认应该是 system class loader 吧？有什么地方改了当前线程的 context class loader? 正常的话当前线程的 context class loader 应该是一个什么 Tomcat 的 class loader 吧

断点显示确实是WebappClassLoader

看一下这个 WebappClassLoader 实例的 delegate 属性是否为 true，有无 Parent Class Loader，如果都是的话，那是调用 Parent Class Loader 的 getResource 方法

delegate为false

我发现在linux上运行任何ClassLoader.getResource(".")都会得到那个奇怪的路径，正在纠结中：http://stackoverflow.com/questions/16317789/thread-currentthread-getcontextclassloader-getresource-has-different-re
