Access activemq Poolable Connection factory as OSGI service - activemq

Question

I am using fuse 6.0 and activemq 5.8. Instead of defining activemq poolable connection factory in each bundle, it makes sense to define in a common bundle and expose it as osgi service. I created blue print file in FUSE_HOME/etc and opened an osgi service like this.
<osgix:cm-properties id="prop" persistent-id="xxx.xxx.xxx.properties" />
<bean id="jmsConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
<property name="brokerURL" value="${xxx.url}" />
<property name="userName" value="${xxx.username}" />
<property name="password" value="${xxx.password}" />
</bean>
<bean id="pooledConnectionFactory" class="org.apache.activemq.pool.PooledConnectionFactory" init-method="start" destroy-method="stop">
<property name="maxConnections" value="${maxconnections}" />
<property name="connectionFactory" ref="jmsConnectionFactory" />
</bean>
<service ref="pooledConnectionFactory" interface="javax.jms.ConnectionFactory">
<service-properties>
<entry key="name" value="localhost"/>
</service-properties>
</service>
and when i try to access this service in both blueprint files and spring text files like this
<reference id="pooledConnectionFactory" interface="javax.jms.ConnectionFactory"/>
bean id="jmsConfig" class="org.apache.camel.component.jms.JmsConfiguration">
<property name="connectionFactory" ref="pooledConnectionFactory"/>
<property name="concurrentConsumers" value="${xxx.concurrentConsumers}"/>
</bean>
<bean id="activemq" class="org.apache.activemq.camel.component.ActiveMQComponent">
<property name="configuration" ref="jmsConfig"/>
</bean>
but I am getting following expection during bundles startup.
Failed to add Connection ID:PLNL6237-55293-1401929434025-11:1201, reason: java.lang.SecurityException: User name [null] or password is invalid.
I even defined compendium definition in my bundles.
How can i solve this problem? any help is appreciated.
I found this online https://issues.apache.org/jira/i#browse/SM-2183
Do i need to upgrade?

It looks to me like you're using the property placeholders incorrectly. First of all, you should know what osgix:cm-properties only exposes the properties at the persistent id that you specify. You can treat it like a java.util.Properties object, and even inject it into a bean as one. This does however mean that it makes no attempt to resolve the properties.
To resolve properties, use spring's property placeholder configurer.
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="properties" ref="prop"/>
</bean>
P.S. The persistent id of cm-properties is the name of the file, not including the file type. You don't need the .properties at the end.
