导致SAXException2的原因:"com.foo.Bar"的实例替换为"java.lang.Object",但"com.foo.Bar"绑定到匿名类型

Question

将现有的jaxb(使用jaxb1.0.1和jaxb 2.0.5)应用程序(在带有jdk5的JBoss 4.3上)迁移到jaxb 2.1.10(随jdk6提供,更新jdk1.6.0_30).

我无法修改客户提供的架构.

我已经从Sun RI删除了jaxws20,jwsdp,jaxp和jaxb jar的所有引用,并且仅使用jdk 6提供的jar.

任何指针？

这可能是由于将Foo对象添加到List<Bar>类型 SOAP 参数而导致的。

几周前我也遇到了同样的异常。我预计会出现编译错误，因此幕后一定有一些丑陋的类型强制允许它发生。我没有进一步调查 - 将Foo's 替换为Bar's （无论如何它们都应该是）解决了问题。
