Comma Separated List From Properties File As Constructor Argument in Spring Bean

I am trying to use below spring injection for list of strings.

<bean name="myBean" class="java.util.HashSet">
    <constructor-arg type="java.util.Collection" value="#{'${my.list.of.strings}'.split(',')}"/>
</bean>

I am getting String "'${my.list.of.strings}'.split(',')" as constructor argument instead of List of Strings.

Is there any Version Issue ? I am using Spring Release 2.5 , spring-beans 2.0.xsd

Please help.
