上下文：

我在Linux机器上使用带有M2E的eclipse 3.7（Java EE版本）。

当我尝试从运行/调试菜单运行jetty服务器时，我收到此错误：

我知道这意味着我在类路径上缺少一个类。麻烦的是它不应该寻找这个类（我没有使用它）。

从Linux控制台运行jetty服务器可以正常工作。

如果我把它作为一个外部工具（在eclipse中）运行，然后连接到调试会话它会运行得很好。奇怪的是，如果我关闭此服务器，然后以原始方式（首次发出错误的方式）运行/调试，它现在运行正常。

另外一条可能相关的信息是Eclipse项目配置从存储库中提取，而Windows用户没有看到这个问题。

这里发生了什么？有办法解决吗？

我终于明白了。所以我发布这个答案给任何遇到同样麻烦的人。

我使用的是IBM JDK，一旦切换到Oracle JDK，这个问题就消失了。所以答案是切换到您正在使用的不同版本的JDK / JVM。
