> This issue was found both when testing with ActiveMQ 5.4.2 and HornetQ 2.1.2 as JMS provider.
The JMS settings is  set in the WSDL file:
> 	<service name="TestJMS">
> 			<port binding="tns:TestBinding" name="Test">
> 			<address destinationStyle="queue" 
> 						jndiConnectionFactoryName="ConnectionFactory" 
> 						jndiDestinationName="dynamicQueues/messageDestination"
> 						xmlns="http://cxf.apache.org/transports/jms">
> 				<JMSNamingProperty name="java.naming.provider.url" value="tcp://localhost:61616?jms.watchTopicAdvisories=false"/>
> 				<JMSNamingProperty name="java.naming.factory.initial" value="org.apache.activemq.jndi.ActiveMQInitialContextFactory"/>
> 			</address>
> 		</port>
> 	</service>
> The issue was found when performing a test with a server and a client both created with
CXF. The client has an infinite loop that performs a request on the server and waits for a
response before the next iteration is executed. After a couple of thousands  of request response
iterations have been performed the JMS provider starts to get very slow and ActiveMQ gets
out of memory if the test is run long enough. First I thought it was a configuration problem
with the JMS provider or a bug in ActiveMQ, but because the same problem exists both with
HornetQ and several configurations of ActiveMQ it seems like it is a problem with CXF. 
> When monitoring ActiveMQ with jconsole it can be seen that when ActiveMQ is set to not
use a thread pool (-Dorg.apache.activemq.UseDedicatedTaskRunner=true), the number of threads
grows while the test is running and no threads seem to be deallocated. When a thread pool
is used the number of threads is quite constant but the amount of memory on the heap still
grows. No leak is observed when a response queue is specified with jndiReplyDestinationName.
So when a temporary queue should be used to send back the replay it seems like one replay
queue is created for every replay and they never get removed.
