Principal name appears twice (sperated by semicolon) in management logs on JMX connection closing/opening
events.

                 Key: QPID-3474
                 URL: https://issues.apache.org/jira/browse/QPID-3474
             Project: Qpid
          Issue Type: Bug
          Components: Java Broker
    Affects Versions: 0.12
            Reporter: Alex Rudyy
            Assignee: Robbie Gemmell
            Priority: Minor


The examples of log entries with principal name displayed twice and separated by semicolon
are displayed below:

{noformat}
2011-09-07 12:42:41,051 INFO  [RMI TCP Connection(3)-169.24.39.206] (Log4jMessageLogger.java:72)
- [mng:N/A(169.24.39.206)] MNG-1007 : Open : User guest;guest
2011-09-07 12:42:44,446 INFO  [RMI TCP Connection(3)-169.24.39.206] (Log4jMessageLogger.java:72)
- [mng:N/A(169.24.39.206)] MNG-1008 : Close : User guest;guest
{noformat}

This problem can be simply reproduced by connecting to broker with Management console and
looking into log files.

This issue occurs due to following reason:

On logging of JMX connection Open/Close events a principal name is taken from JMX connection
id.
In current RMI server implementation the connection id has the following format

{noformat}
rmi://<hostname>:<port> <principal 1>;<principal 2>...<principal
n> <index>
{noformat}

It has the list of principals taken from the subject at the moment of opening the connection.

In current implementation of RMIPasswordAuthenticator on successful authentication an instance
of JMXPrincipal is added to subject in addition to existing UsernamePrincipal which is added
before in AuthenticationManager#authenticate.

As result of this, Subject contains two entries with the same principal name.

On creating a connection Id RMIServerImpl iterates through all principals in subject and adds
them separated by ';' to connection id string.
