Keith Wall reopened QPID-3474:
------------------------------
> Principal name appears twice (separated 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: Keith Wall
> Priority: Minor
> Fix For: 0.15
>
>
> 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.
