There is no leak here. There are three images used by the CTabFolder: arrowLeftImage, arrowRightImage and closeImage These images are used for all tabs (not per tab). Opening an editor and closing an editor will not cause these images to be freed. They will only be freed when the CTabFolder itself is disposed or the images need to be recreated because the size of the tabs has changed. Even when all tabs have been disposed, the CTabFolder itself is not disposed and the images are still around. It would be a waste to dispose the images when there are no tabs and recreate them when the next tab is created since that is done very frequently in eclipse.
