Gotta include those .g files, man.
Don't be slighting the xpath sources... ;)

Honestly, try this:
Remove the comparators and recompile. I don't think
they are truly used right now. At least, the original
werken.xpath never actually used them.
Else, just do _orders = new HashMap(0); or maybe we can create
a singleton empty-map:
public class EmptyMap extends HashMap
{
private static Map _instance = new EmptyMap();
public static Map getInstance()
{
return _instance;
}
private EmptyMap()
{
super( 0 );
}
}
