The javadoc for Window.setIconImages() method should be updated.

could it be my mistake in assigning the priority level? Not sure if the impact is medium or low. In the latter case the priority could be reduced to P4

can't be tbd_major as P3 introduced in 9

There is also a potential ambiguity here: Let us have a list of multi-resolution images having the following resolution variants: iconsList = { icon1 {low - 16x16, high - 32x32} icon2 {low - 32x32, high - 64x64} } What is the correct icon after "setIconImages(iconsList)" call, if the size 32x32 fits and the scale = 2? "icon1-high" or "icon2-low"? The initial (naive) expectation is that "icon1-high" should be chosen in case when the scale is greater than one. Docs: "If the list contains several images of the same size, the first will be used." What is the "1st" here: "icon1-high" or "icon2-low"? Probably this should be specified for multi-res. images

The issue isn't caused by the above ambiguity. Please compile/run the 2nd attached 'MultiResIconTest.java' using scale = 1, 2, 4. The image color will be red/green/blue (as expected). the icon is always red (nok).

please see also 'artifacts.png'. does this issue duplicate JDK-8069348? If no, it shoul be filed separately.
