An ObjectCreateRule needs to know the type of object to create, not a method
to call.  You need to let Digester create an object and push it on the
stack, and calling createTreeMap won't do that.

I thought...
   digester = new Digester();
   digester.setValidating(false);
   digester.addObjectCreate("DATA/VERSION", "TreeMap.class");
   digester.addCallMethod("DATA/VERSION/ITEM", "put", 2);
   digester.addCallParam("DATA/VERSION/ITEM", 0, "NAME");
   digester.addCallParam("DATA/VERSION/ITEM", 1);
   return digester.parse(file);

It should create a TreeMap and then call 'put' with the value of the NAME
attribute and the body of the <ITEM> tag as the name/value pair.  Some of
the method params may be switched around, double check the signatures.
