>             Project: Cassandra
>          Issue Type: Bug
>         Environment: Ubuntu Trusty, Oracle JDK 1.8.0_102-b14, IPv6-only host

> A Cassandra node using *default* configuration is unable to start on *IPv6-only* machine
with the following error message:
> {code}
> ERROR [main] 2016-08-13 14:38:07,309 CassandraDaemon.java:731 - Bad URL path: :0:0:0:0:0:1/jndi/rmi://0:0:0:0:0:0:0:1:7199/jmxrmi
> {code}
> The problem might be located in {{JMXServerUtils.createJMXServer()}} (I am not sure,
because there is no stack trace in {{system.log}}):
> {code:java}
> String urlTemplate = "service:jmx:rmi://%1$s/jndi/rmi://%1$s:%2$d/jmxrmi";
> ...
> String url = String.format(urlTemplate, (serverAddress != null ? serverAddress.getHostAddress()
: "0.0.0.0"), port);
> {code}
> IPv6 addresses must be surrounded by square brackets when passed to {{JMXServiceURL}}.
> Disabling {{LOCAL_JMX}} mode in {{cassandra-env.sh}} (and enabling JMX authentication)
helps.
