Issue

We use the following in a cxf.xml file at the server level in order control some CXF behavior. For example:

<cxf:properties>
  <beans:entry key="set-jaxb-validation-event-handler" value="false" />
  <beans:entry key="faultStackTraceEnabled" value="true"/>
</cxf:properties>

We modified it in order to be able to control the behaviour using system properties like this:

<cxf:properties>
  <beans:entry key="set-jaxb-validation-event-handler" value="${cxf.set.jaxb.validation.event.handler:false}" />
  <beans:entry key="faultStackTraceEnabled" value="${cxf.faultStackTraceEnabled:true}"/>
</cxf:properties>

For instance, we want the value true to be set as a default value for the key faultStackTraceEnabled, but we want to be able to override the default value.

But when I use this syntax ${cxf.faultStackTraceEnabled:true}, the stack trace stopped being sent to the client side (i.e. the property wasn't being resolved correctly).

What is wrong with how I'm using ${cxf.faultStackTraceEnabled:true}?
