我不完全确定这个Restlet错误是什么：

解决方案是使用org.restlet.gae 

    <dependency>
        <groupId>org.restlet.gae</groupId>
        <artifactId>org.restlet</artifactId>
        <version>2.2.1</version>
    </dependency>
    <dependency>
        <groupId>org.restlet.gae</groupId>
        <artifactId>org.restlet.ext.servlet</artifactId>
        <version>2.2.1</version>
    </dependency>
    <dependency>
        <groupId>org.restlet.gae</groupId>
        <artifactId>org.restlet.ext.jackson</artifactId>
        <version>2.2.0</version>
    </dependency>
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>servlet-api</artifactId>
        <version>2.5</version>
    </dependency>

我遇到了同样的错误，第一个解决方案对我没有帮助。

我的项目中的问题是还有另一个maven依赖项，它也使用了一个reslet依赖项，只使用了不同的版本（这就是为什么你得到错误＆＃34; java.lang.VerifyError：操作数堆栈上的错误类型＆ ＃34）。

解决方案是让他们同意这种依赖关系（我的情况很容易，其他依赖关系并没有被使用，只是让我的生命伤心了半天）。

如果确实需要该依赖项，请尝试使用与依赖项所使用的相同的restlet版本。
