Please review the file in the package.

I run the following code:

BufferedImage systemImage = ((IPictureFrame)presentation.getMasters().get_Item(0).getShapes().get_Item(0)).getPictureFormat().getPicture().getImage().getSystemImage();

The line of code run over 45 minutes and crash the app.
I found the image content type is image/x-emf. How to fix the problem? Any help would be grateful.
