【问题描述】：
在 Apache Camel 上开发了一个小组件，用作多播器，将传入消息转发到一组端点。
此组件正在 WebLogic 服务器上运行。
版本详情：
- JDK：1.6 / 1.7.0_75
- Apache Camel:2.14.1
- WebLogic：10.3.6
提出了一项新要求，即在运行时修改目标端点集，而无需重新构建和重新部署组件。
第一个想法是使用 Apache Camel 提供的 JMX 功能来实现这一点。
JConsole 用作 JMX 客户端。
jconsole -J-Djava.class.path=%JAVA_HOME%\lib\jconsole.jar;%JAVA_HOME%\lib\tools.jar;%WL_HOME%\server\lib\wlfullclient.jar;%WL_HOME%\server\lib\wljmxclient.jar -debug
作为我们使用的连接字符串：
service:jmx:rmi:///jndi/iiop://localhost:7001/weblogic.management.mbeanservers.runtime
管理对象路由 (see available docu) 中的方法 updateRouteFromXML 似乎适合这项工作。
为了测试这个方法，首先调用dumpRouteAsXml来得到一个XML格式的要修改的路由的描述。
路线示例如下所示：
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<route customId="false" id="route7" xmlns="http://camel.apache.org/schema/spring">
<from uri="servlet:///TESTServer"/>
<convertBodyTo type="[B" id="convertBodyTo7"/>
<removeHeader headerName="CamelHttpPath" id="removeHeader7"/>
<multicast parallelProcessing="true" timeout="3000" id="multicast7">
<to uri="http://ip1:8007/IOCServer?bridgeEndpoint=true&throwExceptionOnError=false" id="to19"/>
<to uri="http://ip2:8007/IOCServer?bridgeEndpoint=true&throwExceptionOnError=false" id="to20"/>
<to uri="http://ip3:8007/IOCServer?bridgeEndpoint=true&throwExceptionOnError=false" id="to21"/>
</multicast>
</route>
此 xml 用作 updateRouteFromXML 的输入：
<route customId="false" id="route7" xmlns="http://camel.apache.org/schema/spring">
<from uri="servlet:///TESTServer"/>
<convertBodyTo type="[B" id="convertBodyTo7"/>
<removeHeader headerName="CamelHttpPath" id="removeHeader7"/>
<multicast parallelProcessing="true" timeout="3000" id="multicast7">
<to uri="http://ip1:8007/IOCServer?bridgeEndpoint=true&throwExceptionOnError=false" id="to19"/>
<to uri="http://ip2:8007/IOCServer?bridgeEndpoint=true&throwExceptionOnError=false" id="to20"/>
<to uri="http://ip3:8007/IOCServer?bridgeEndpoint=true&throwExceptionOnError=false" id="to21"/>
</multicast>
</route>
我们尝试了几种变体（例如没有 xml 标头）。
但总是得到相同的异常：

是否有人通过 JMX 成功调用了 UpdateRouteFromXml？
使用 jdk1.7.0_75 进行相同的错误测试
