Re: ERXModelGroup(EOModelGroup).fetchSpecificationNamed(String, String)

In ERXModelGroup there is a method:

     /**
      * Overridden to use our model class in the runtime.
      */
     public EOModel addModelWithPathURL(URL url) {
         EOModel model = null;
         if(patchModelsOnLoad) {
             model = new Model(url);
         } else {
             model = new EOModel(url);
         }
         addModel(model);
         return model;
     }

The second time "new EOModel(url)" is called, with the URL to the 
QsdCoreData eomodel, it fails. I can't see what's going on inside that 
constructor...

(Kind of assume that means it is not a WONDER problem.)

Did a CVS diff on QsdCoreData compared to one month ago and three months 
ago. Nothing has changed.

The full stack trace I get is:
