Spring PropertyPlaceholderConfigurer and MongoDB replica-set - spring

Question

In my spring context, I am using PropertyPlaceholderConfigurer to load up properties from env.properties:
<bean id="propertyPlaceholderConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>classpath:env.properties</value>
</list>
</property>
</bean>
In my env.properties I have the following:
db.mongo.replicationset=server1:1111, server2:2222, server3:3333
And finally, in spring context:
<mongo:mongo id="mongo" replica-set="${db.mongo.replicationset}">
<mongo:options slave-ok="true"/>
</mongo:mongo>
I am seeing java.lang.ArrayIndexOutOfBoundsException:
ERROR: org.springframework.web.context.ContextLoader - Context initialization failed
org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from class path resource [root-context.xml]; nested exception is java.lang.ArrayIndexOutOfBoundsException: 1

Everything works with hard-code replication-set as the following:
<mongo:mongo id="mongo" replica-set="server1:1111, server2:2222, server3:3333">
<mongo:options slave-ok="true"/>
</mongo:mongo>
My guess is that colon or comma might be special characters for PropertyPlaceholderConfigurer, so can not be used.
How could I make this configuration work with PropertyPlaceholderConfigurer and a properties file.
Edit
This issue is fixed for spring-data-mongodb:1.0.0.RELEASE and spring-data-mongodb:1.1.0.M1

This is actually an bug in the latest Spring-data-mongo M5 milestone.

The following works:
<mongo:mongo
replica-set="${mongo.replicaset.1}:${mongo.replicaset.1.port},${mongo.replicaset.2}:${mongo.replicaset.2.port},${mongo.replicaset.3}:${mongo.replicaset.3.port}">
