Consider a broker that is configured for

 <systemUsage>
  <systemUsage sendFailIfNoSpace="true">
  ...
</systemUsage>

and raises an exception in case the persistence store is full.

Now, when using a CXF client with JMS transport and request/reply communication, the broker may raise an JMSException in case it cannot take any more message because the store is full.

While the exception is caught and handled in org.apache.cxf.transport.jms.JMSConduit.sendExchange():

            if (exchange.isOneWay()) {
                sendMessage(request, outMessage, null, null, closer, session);
            } else {
                sendAndReceiveMessage(exchange, request, outMessage, closer, session);
            }
        } catch (JMSException e) {
            // Close connection so it will be refreshed on next try
-->       ResourceCloser.close(connection);
            this.connection = null;
            this.staticReplyDestination = null;

and CXF tries to close the JMS connection, this call will fail with this message

INFO: failed to delete Temporary Queue "temp-queue://ID:Mac.fritz.box-58171-1529310181545-1:1:1" on closing pooled connection: A consumer is consuming from the temporary destination

It fails because the call to ActiveMQConnection.close(), first tries to delete any temporary destinations. These however cannot be deleted because there is still a consumer registered on this temp destination. Hence above message.

The ActiveMQConnection remains open, the temp destination is not cleared either but remains registered under the ActiveMQConnection.
