The simple implementation, like this, results in drag and drop exceptions.

tv = TreeViewerSWTFactory.createTreeViewer(parent, rootElement);

There was a suggestion in an article describing TreeViewerSWTFactory which described a way to use customization, which I could use to fix this. It took a little digging to figure out, so I'm posting it.

tv = TreeViewerSWTFactory.fillDefaults(parent, rootElement).
customizeDragAndDrop(new DNDProvider(){

@Override
public boolean hasDND() {
// TODO Auto-generated method stub
return false;
}
... the rest of the generated overrides
}).create();
