Java 我应该还是不应该'；我是否使用带有hornetq 2.4.1的CachingConnectionFactory

基于长期以来关于在hornetq中使用JMSTemplate的信息，我们在连接到服务器时一直在使用CachingConnectionFactory。下面是一个配置示例，与我们正在使用的配置非常类似：

<bean id="jmsConnectionFactory" class="org.hornetq.jms.client.HornetQJMSConnectionFactory">
    <constructor-arg name="ha">
        <value>false</value>
    </constructor-arg>
    <constructor-arg name="initialConnectors">
        <bean class="org.hornetq.api.core.TransportConfiguration">
            <constructor-arg value="org.hornetq.core.remoting.impl.netty.NettyConnectorFactory" />
            <constructor-arg>
                <map key-type="java.lang.String" value-type="java.lang.Object">
                    <entry>
                        <key>
                            <util:constant static-field="org.hornetq.core.remoting.impl.netty.TransportConstants.HOST_PROP_NAME"/>
                        </key>
                        <value>${message-server.host}</value>
                    </entry>
                    <entry>
                        <key>
                            <util:constant static-field="org.hornetq.core.remoting.impl.netty.TransportConstants.PORT_PROP_NAME"/>
                        </key>
                        <value>${message-server.port}</value>
                    </entry>
                </map>
            </constructor-arg>
        </bean>
    </constructor-arg>
</bean>

<bean id="connectionFactory"
    class="org.springframework.jms.connection.UserCredentialsConnectionFactoryAdapter">
    <property name="targetConnectionFactory" ref="jmsConnectionFactory" />
    <property name="username" value="${message-server.user-name}" />
    <property name="password" value="${message-server.password}" />
</bean>

<bean id="caching.connectionFactory" class="org.springframework.jms.connection.CachingConnectionFactory">
    <property name="targetConnectionFactory" ref="connectionFactory" />
    <property name="sessionCacheSize" value="${session-cache}" />
    <property name="cacheProducers" value="${cache-producers}" />
    <property name="cacheConsumers" value="${cache-consumers}" />
</bean>

<bean id="transactionManager" class="org.springframework.jms.connection.JmsTransactionManager">
    <property name="connectionFactory" ref="connectionFactory" />
</bean>

<!-- Input Integration -->

<bean id="inputTopic" class="org.hornetq.jms.client.HornetQTopic">
    <constructor-arg>
        <value>${topicName}</value>
    </constructor-arg> 
</bean>
<int-jms:message-driven-channel-adapter connection-factory="connectionFactory"
    destination="inputTopic" 
    transaction-manager="transactionManager"
    pub-sub-domain="true" 
    channel="command.serialized.objectInputChannel" />

假的
${message server.host}
${message server.port}
${topicName}

这已经为我们工作了将近3年了。当尝试升级到最新的hornetq库时，我们会遇到类似以下情况的异常：
