我最近将AppEngine应用程序从Java 6转换为Java 7，我遇到以下错误：

我的应用程序配置是
使用Java 1.6，应用程序编译并运行。使用Java 1.7，应用程序可以编译，但在运行时会抛出上述错误。
我尝试使用其他人（Jersey setup on app engine）建议的以下球衣配置但没有用。
<init-param>
<param-name>com.sun.jersey.config.feature.DisableWADL</param-name>
<param-value>true</param-value>
</init-param>
有谁知道造成这种情况的原因以及如何解决这个问题？
答案 0 :(得分：2)
看起来像jersey-json带来了不同版本的Jaxb。排除它解决了这个问题。
