> h3. Problem description
> In JMSFactory.createConnection(JMSConfiguration):
> {code}public static Connection createConnection(JMSConfiguration jmsConfig) 
> throws JMSException {
>       String username = jmsConfig.getUserName();
>       ConnectionFactory cf = jmsConfig.getConnectionFactory();
>       Connection connection = username != null 
>               ? cf.createConnection(username, jmsConfig.getPassword())
>               : cf.createConnection();
>       if (jmsConfig.getDurableSubscriptionClientId() != null) {
>               
> connection.setClientID(jmsConfig.getDurableSubscriptionClientId());
>       }
>       return connection;
> }{code}
> there is no exception handling if the clientID fails to be set. Such an 
> exception would exit this method without passing the reference to the 
> just-opened JMS connection to exception handling code 
> (JMSDestination.createTargetDestinationListener()).
> Moreover, JMSDestination.restartConnection() keeps on starting new 
> connections (there is no max attempt restriction!) until it creates one 
> without an exception thrown in the process.
> Now, if the clientID is already connected to the ESB, this creation of new 
> connection will last until server resources are no longer available to the 
> JVM.
> h3. Possible solution
> # Close the connection if it's not possible to set the specified clientID at 
> the time:
> {code}public static Connection createConnection(JMSConfiguration jmsConfig) 
> throws JMSException {
>       String username = jmsConfig.getUserName();
>       ConnectionFactory cf = jmsConfig.getConnectionFactory();
>       Connection connection = username != null 
>                       ? cf.createConnection(username, 
> jmsConfig.getPassword()) 
>                       : cf.createConnection();
>       if (jmsConfig.getDurableSubscriptionClientId() != null) {
>               try {                                   
> connection.setClientID(jmsConfig.getDurableSubscriptionClientId());
>               } catch (InvalidClientIDException e) {
>                       connection.close();
>                       throw e;
>               }
>       }
>       return connection;
> }{code}
> # Add a setting to restrict the maximum attempts to restart the connection in 
> JMSDestination.restartConnection() A configurable value would be best, but 
> even a hardcoded.. anything but the practically endless loop ;-)
