我是GAE的老用户，但最近在我的OS X更新到Mavericks DP4和Java SDK（1.6,1.7,1.8）和Goolge App之后Engine SDK（1.8.1,1.8.2），我无法再启动我的GAE应用程序，堆栈跟踪看起来完全混乱，你知道为什么吗？它在我的本地机器上运行得很好，但是一旦部署到主机平台上，它就无法启动，每个请求的结果都会导入下面的堆栈跟踪，项目配置为 1.使用JDK1.7（另外，我试过1.6 ） 2.使用SDK1.8.2（也试过1.8.1，没有运气）Google App Engine - javax.servlet.UnavailableException：初始化失败

空指针异常，非法参数异常（可能来自空指针参数）。 –
但最终它是由这个异常引起的：“来自servlet的未捕获的异常 javax.servlet.UnavailableException：初始化失败。”，您怎么看？ – MrW
作为解决方案，我最终使用了一个虚拟的win7来上传相同的代码。一切都很好。我不确定这是否是一些MAC-Java冲突，但我非常怀疑这一点。 – MrW
