I admit I can't understand what the test is doing, and I don't have to time to study the test thoroughly. However, I'm still for documenting null and invalid parameters under a separate bug id; under this bug id modify `Image.setImage` to accept `null` as it's reported in the bug ([JDK-8159055](https://bugs.openjdk.org/browse/JDK-8159055)) and as it was done in this PR initially. ------------- Marked as reviewed by aivanov (Reviewer).
