Catastrophic Error trying to use com4j to add artwork from file to iTunes IITrack object

Question

Using Com4j with iTunes, no problem adding various text values to a IITrack object but if I try and add artwork with

if(iTunesTrack.artwork().count()==0)
{
  String path = new File(new File(song.getFilename()).getParent(),"folder.jpg").getPath();
  if(Files.exists(Paths.get(path)))
  {
      iTunesTrack.addArtworkFromFile(path);
  }
}

it fails with

The COM4j interfaces were built from my version of iTunes so they exist, I don't know if I am doing anything wrong or if its broken, I ve had tried on a number of jpogs all with the same result. I check the files exist and indeed the error is different if try to add a nonexistent file.
