Am I going crazy but are the "free" downloadable RC1 jars mismatched????? (I only say free because I am not sure if its included in the jars that the paying customers get)

the bi-platform-engine-services uses org.pentaho.platform.api.util.XmlParseException of which is NOT in the released pentaho-bi-platform-api-2.0.0-RC1.jar but its defined in the code from svn. Now am I missing something because I would think a lot of people would have found this. Or maybe its because I obviously have an xml problem with my xaction and everyone is better at xactions. Or does everyone build their own jars?
