> 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.
