java - 轻松异常；向 ResteasyBootstrap 类的监听器实例发送上下文初始化事件的异常

Question

当我尝试获取此休息服务时收到此错误:

JBWEB000287: Exception sending context initialized event to listener instance of class org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap: java.lang.RuntimeException: RESTEASY001745: Unable to find a public constructor for class org.jboss.resteasy.core.AsynchronousDispatcher

我使用的是Jboss 6.4，我看不出是什么产生了这个错误，看起来一切正常。有什么想法吗？

服务休息:

@Path("/message")
public class MessageService {
    @GET
    @Path("/{name}")
    public Response getMessage(@PathParam("name") String name) {
        String message = "Hello " + ((name != null) && (name.length() > 0) ? name : "anonymous");

        return Response.status(200).entity(message).build();
    }
}

尝试将 Resteasy 依赖项的范围更改为提供的。 Resteasy 已经与 JBoss 捆绑在一起，因此该问题可能是由于版本冲突或类似原因引起的。
