Thank you, Alexey!

Root cause: White borders around ESL are seen because EmptyBorder is set to JScrollPane which contains JList. OS X is different from Windows and Linux in that JPanel for tab is not opaque*, and setOpaque(false) is called recursively on all the components. For some reason, EmptyBorder is rendered in white color in this situation. This issue could also be reproduced on Windows and Linux if you make JPanel not opaque. This is fixed by wrapping JScrollPane in additional JPanel and setting the border on JPanel rather than JScrollPane. * I admit JPanel for tabs should be transparent on Windows and Linux too.

Problem is reproducible on 7u71 as well. Both OS X - ESL scrollbar 3.png and OS X - ESL scrollbar 4.png look good. You understood me correctly. Yes, the problem was in white stripe at the right border of the list.

Alexander, Thank you for clarification. That's expected because JDK-8038463 is in 7u80 only. Please note JDK-8038463 must always be accompanied by JDK-8048906. Further UI improvements are provided in JDK-8050016, however it's not required. I recommend backporting all three together.

Unless I have more detailed description from Alexander, I consider this bug as fixed by changes to JDK-8038463.

I've attached two images of JDK build with JDK-8038463 fix. ESL does not have white borders with that fix. The white borders are the only thing that I can think about fixing here. The list is set to *always* display the scroll bar, so if you have less than 4 items in the list, the scroll bar is displayed in disabled state, see OS X - ESL scrollbar 4.png. If the list contains 4 or more items, the scroll bar has the thumb under OS X or has up/down button under Windows/Linux as the thumb does not fit.
