Help! Exception when trying to use Float

Question

Hi. I'm about to lose my mind trying to fix this exception:
SubsampleAverage - Parameter value's class (java.lang.Float) is not an instance of the parameter class (java.lang.Double) for parameter "scaleX".It's being thrown by this code,
public BufferedImage resizeImage(InputStream inputStream)
    BufferedImage resizedImage = null;
    try {
      SeekableStream stream = SeekableStream.wrapInputStream(inputStream, true);
      RenderedOp newImage = JAI.create("stream",stream);
      ((OpImage)newImage.getRendering()).setTileCache(null);
      float scale = targetWidth / newImage.getWidth();
      ParameterBlock pb = new ParameterBlock();
      pb.addSource(newImage);
      pb.add(scale);
      pb.add(scale);
      RenderingHints qualityHints =
        new RenderingHints(RenderingHints.KEY_RENDERING, RenderingHints.VALUE_RENDER_QUALITY);
      resizedImage = (JAI.create("SubsampleAverage",pb,qualityHints)).getAsBufferedImage();
    catch (Exception e)
      this.error = e.getMessage();
    return resizedImage;
  }

Answer 1

I suspect scale should be a double then.
