Could not find the exact root cause so predicting it to be an issue with icons not loaded where _resolutionVariants_ map is empty in _public Image getResolutionVariant(double width, double height) _. Hence proposing a null check before accessing _getWidth()_. Fix is tested in CI system.

I am pretty sure that the NPE reported recently in the comment in JBS is unrelated to the AssertionError reported initially. It is better to file separate issue.
