property substitution with default doesn't work?

[tunkul]

So in the /etc/env-properties file, i have:

port=1234

And the substitution in the "testit" bean works fine. Ie, i end up with 1234 in my "testit" bean.

<!-- use placeholders where we might want a JVM argument -->
<bean id="propertyPlaceholder"
class="org.springframework.beans.factory.config.Pr opertyPlaceholderConfigurer"
p:ignoreResourceNotFound="true"
p:systemPropertiesModeName="SYSTEM_PROPERTIES_MODE _OVERRIDE" >
<property name="locations">
<list>
<value>file:/etc/env-overrides.properties</value>
</list>
</property>
</bean>

<bean id="testit" class="java.lang.String">
<constructor-arg index="0" value="${port}" />
</bean>

However, if i change the bean def to use a default value:

<bean id="testit" class="java.lang.String">
<constructor-arg index="0" value="${port:666}" />
</bean>

I end up with port set to 666, instead of 1234. Of course, the intent is to use 666 if nothing is found in the property file. But i do have "port" defined in the property file, but i end up with the default of 666.

How is this defaulting supposed to work?

I tested with <context: property-placeholder> and annotation style injection in Spring 3, the default works just fine.
