SystemPropertiesService does not properly generate server path on windows

<mbean code="org.jboss.varia.property.SystemPropertiesService"
name="jboss:type=Service,name=SystemProperties">
<attribute name="Properties" replace="false">
log.file.location=${jboss.server.home.dir}/log
</attribute>
</mbean>

The jboss.server.home.dir is not string replaced properly on windows.

I suspect it to be related to the Property class in the Jboss common module.
