> Orphaned JMS connections created in endless loop
> ------------------------------------------------
>
> Key: CXF-6454
> URL: https://issues.apache.org/jira/browse/CXF-6454
> Project: CXF
> Issue Type: Bug
> Components: JMS, Transports
> Affects Versions: 3.0.5
> Reporter: Waldemar Szostak
> Assignee: Christian Schneider
> Priority: Critical
> Fix For: 3.0.7, 3.1.7, 3.2.0

> 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 ;-)
