Answer 1

原因是JMX绑定了一个IPv6地址，格式错误。解决办法：

方法1. 若不需要IPv6地址，则将external.vmoptions中的-Djava.net.preferIPv4Stack设为true，用IPv4地址。

方法2. external.vmoptions中加参数绑定IPv6   -Djava.rmi.server.hostname=[fe80::b0ce:dbf7:2644:dfca]  记得要有中括号。

注意:TongWeb一些老版本还需在conf/tongweb.xml中<jmx-service port="7200" address="[fe80::b0ce:dbf7:2644:dfca]" protocol="rmi"/>绑定IP。
