> This is a regression introduced due to fix for JDK-8208638. The default behaviour for ImageView is to load an image asynchronously. Hence, it uses the ImageHandler::imageUpdate to get the updates to the image being loaded. That will set the width and height of the image view. ImageView::updateImageSize does not alter the width and height in this case. When a JToolTip is created and html text set as tooltip, internally, the image is requested to be loaded synchronously, and in this case, ImageView::updateImageSize is the only way to calculate the image size. Since the width and height were not specified in the tooltip, the image was not being drawn.
> The fix is to check if the image is requested to be loaded synchronously, and if so, then do the same calculation as for the fix for JDK-8208638, which will provide valid image width and height, additionally also taking care of the scaling issues fixed for JDK-8208638.
