我们在Wildfly 8.2中使用Twiddle独立https://developer.jboss.org/people/arnoldjohansson/blog/2012/04/14/twiddle-standalone进行JMX监控。根据自述文件说明，我们已下载链接https://github.com/swesource/twiddle-standalone中提供的zip文件，并在twiddle.sh中设置JBOSS_HOME。当我使用standalone.sh启动wildfly服务器并尝试运行以下命令时
twiddle.sh -s service：jmx：remoting -jmx：//127.0.0.1：9999 get java.lang：type = ClassLoading
我得到如下错误：
