I'm trying to scale an image after upload (in the doPost method). The
blob key seems to be ok and the image is served after the upload.

Image oldImage = ImagesServiceFactory.makeImageFromBlob(bk);
double aspectRatio = (double) oldImage.getWidth()  / (double)
oldImage.getHeight();


->

java.lang.UnsupportedOperationException: No image data is available.
