`ImageIcon` changes look good to me.

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.
