WARN if deployment descriptor has ${...} but *property-replacement=false
By default the property replacement defaults to true for jboss deployment descriptors and false for annotations and spec deployment descriptors:
"annotation-property-replacement" => false, "jboss-descriptor-property-replacement" => true, "spec-descriptor-property-replacement" => false,
In the persistence.xml for example, there is a freeform <properties> with properties that can change over time and default values. If *property-replacement is false , then ${...} is passed to the DUP to configure and can cause problems such as in this hibernate property which changed from default value of false to true and the user was unaware that system property substitution was not occurring because they had not enabled it.
