Camel The application attempted to use a JMS session after it had closed the session

问题

I am new to camel and I am attempting to write an app that bridges Websphere MQ and Active MQ on JBoss EAP 7. The app deploys successfully works, I can drop messages on the Websphere queue, and it gets picked up by Active MQ. However I see error messages in the log showing it is attempting to use a connection after it is open.

15:48:57,814 ERROR [org.jboss.jca.core.connectionmanager.listener.TxConnectionListener] (Camel (camel) thread #1 - JmsConsumer[I0_TEST]) IJ000315: Pool IbmMQQueueFactory has 1 active handles

Cause: Local JMS transaction failed to commit; nested exception is com.ibm.msg.client.jms.DetailedIllegalStateException: MQJCA1020: The session is closed.
The application attempted to use a JMS session after it had closed the session.
Modify the application so that it closes the JMS session only after it has finished using the session.

Here is my applicationContext.xml

<bean id="jmsConnectionFactory" class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="jndiName" value="java:/ConnectionFactory" />
    <property name="lookupOnStartup" value="false" />
    <property name="cache" value="true" />
    <property name="proxyInterface" value="javax.jms.ConnectionFactory" />
</bean>

<bean id="jmsTransactionManager"
    class="org.springframework.transaction.jta.JtaTransactionManager">
    <property name="transactionManagerName" value="java:/TransactionManager" />
</bean>

<bean id="jms" class="org.apache.camel.component.jms.JmsComponent">
    <property name="connectionFactory" ref="jmsConnectionFactory" />
    <property name="transacted" value="true" />
    <property name="transactionManager" ref="jmsTransactionManager" />
</bean>

<bean id="wmqConnectionFactory" class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="jndiName" value="java:/jms/IbmMQMsgQCF" />
    <property name="lookupOnStartup" value="false" />
    <property name="cache" value="true" />
    <property name="proxyInterface" value="javax.jms.ConnectionFactory" />
</bean>

<bean id="wmqTransactionManager"
    class="org.springframework.transaction.jta.JtaTransactionManager">
    <property name="transactionManagerName" value="java:/TransactionManager" />
</bean>

<bean id="wmq" class="org.apache.camel.component.jms.JmsComponent">
    <property name="connectionFactory" ref="wmqConnectionFactory" />
    <property name="transacted" value="true" />
    <property name="transactionManager" ref="wmqTransactionManager" />
</bean>


<bean id="routerlogger" class="org.jboss.as.quickstarts.mdb.RoutLogger" />

<camelContext trace="true" id="camel"
    xmlns="http://camel.apache.org/schema/spring">

    <route>
        <from uri="wmq:websphereQueue"/>
        <setExchangePattern pattern="InOnly"/>
        <to uri="jms:activeQueue" pattern="InOnly" />
    </route>
</camelContext>

Its a simple app, trying to determine what I'm missing.

I found this JBossDeveloper bug "JBEAP-2344: UserTransaction commit(), rollback() closes connection in Websphere MQ 7.5" which looks like it describes your issue and has comments pointing to documentation update "JBEAP-3535: Documentation: Add note about connection close on commit() and rollback() to Deploy the WebSphere MQ Resource Adapter subchapter".

Could you please add a note, that setting tracking="false", solves problem with WebSphere MQ 7.5 and 8, where method commit() or rollback() on UserTransaction closes any JMS connections which was part of this transaction. This part is related to documenting known limitation of WebSphere MQ in JBEAP-3142.
