* This class provides code that maps back and forth between a {@link PropertyMap} and

* java.util.Properties. Its associated PropertiesMetaType may or may not define
* member property names; since the RHQ Configuration system assumes a
* PropertyDefinitionMap either defines none of its member properties (i.e. an "open
* map") or defines all of them, we just ignore the PropertiesMetaType and always map
* to an open map.
