Xsd 运行Axis2 WSDL2Java的SchemaParsingConfig.setFeature（）中的NullPointerException

在日常工作过程中，我尝试使用本文中的WSDL和XSD：

作为生成一些java代码的模板。我的愿望是使用生成的java代码以某种方式验证我（将要）手工编写的WSDL和模式是否合理合理。问题是，当我跑步时（比如）：

我得到一个例外：

这个示例WSDL是否存在已知问题

Axis2（1.5版）WSDL2Java中是否存在缺陷？（很明显，如果有一条关于丢失数据的错误消息，而不是空指针/引用抛出，那就太好了）

没人关心，项目暂停，“WADL”（WADL2Java）在休息时就不那么糟糕了……我投票结束了我自己的问题。请帮我杀了这个僵尸！
