Meanwhile i changed many stuff in jface.
Nevertheless, works now, with doing this:

class FileTreeContentProvider : ITreeContentProvider
{
     Object[] getChildren(Object element)
     {
         try{
             Object[] kids;
             foreach( item; cast(FilePath) elements ){
                  kids ~= FilePath.from(item);
             }
             return kids;
         }
         catch( Exception e ){
             return null;
         }
     }
     ....

See also the jface/FileTreeViewer example.
A problem is, the LabelProvider gets completely ignored. This is why the 
icons and name do not show up properly.
