   The main problem is that the Image.SCALE_DEFAULT hint is used to retrieve a scaled image from Image.getScaledInstance() method.
    It always uses the ReplicateScaleFilter for images which getScaledInstance() method has not been overridden.
    The ReplicateScaleFilter creates a lot of arrays and consumes the CPU during the image parsing.

   The better fix is to introduce the new Image.SCALE_CUSTOM hint which can be used to get a scaled image and does not use filters by default.
