selector not working for sonic mq message-driven-channel-adapter

Question

I have this spring integration config. The JMS broker is Sonic MQ. For some reason a connection cannot be established if I add a selector. I get lots of connection refreshed logs. It works fine without the selector. Is this a know issue for Sonic MQ in Spring integration? I am unable to find any examples of a Sonic MQ config in spring integration.

<int-jms:message-driven-channel-adapter
    id="itemListener" 
    channel="jmsInChannel"  
    destination="itemTopic"
    selector="Content_Type = 'application/json'"
    connection-factory="sonicConnectionFactory"
    subscription-durable="false" 
    durable-subscription-name="item-subcription" 
/>

<bean id="sonicConnectionFactory"class="progress.message.jclient.ConnectionFactory">
    <property name="ConnectionURLs" value="${jms.sonic.urls}" />
    <property name="DefaultUser" value="${jms.sonic.username}" />
    <property name="DefaultPassword" value="${jms.sonic.password}" />
    <property name="ReconnectInterval" value="30" />
    <property name="ReconnectTimeout" value="0" />
</bean>
