[mdr-users] XMI reading fine, but empty result collection

Hi,

I'm having a strange problem here. I'm just trying to load the UML 1.4 metamodel into MDR, and although the XMI reading seems to succeed (no error), the resulting collection is empty:

 MDRepository repo = MDRManager.getDefault().getDefaultRepository();
      repo.beginTrans(true);
      RefPackage mmHandle = repo.createExtent("testMM");

      XMIReader reader = XMIReaderFactory.getDefault().createXMIReader();
      java.util.Collection col = reader.read("jar:file:/usr/local/andromda-bin-3.0-RC1-SNAPSHOT/lib/jmi/jars/jmiuml-1.4di.jar!/M2_DiagramInterchangeModel.xml",
          mmHandle);
      System.out.println(col.size());

This outputs '0'.

As logging output, I get the following:

[org.netbeans.mdr.Logger] Storage factory: org.netbeans.mdr.persistence.memoryimpl.StorageFactoryImpl

So you'd think everything is loaded all right...

Maybe the storage version exception means something?

Thanks,
