After a month of discussions, that solution has been abandoned, instead it is stated that `Image.setImage` will throw `NullPointerException` if `image` parameter is `null`. I think the type of JDK-8159055 should be changed to *bug*. ------------- PR Comment: https://git.openjdk.org/jdk/pull/25767#issuecomment-3129858458
