-----------------------------------------

             Summary: Unable to start on IPv6-only node with local JMX
                 Key: CASSANDRA-12454
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-12454
             Project: Cassandra
          Issue Type: Bug
         Environment: Ubuntu Trusty, Oracle JDK 1.8.0_102-b14, IPv6-only host
            Reporter: Vadim TSes'ko


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.
