<Swing Dev> [9] Review request for 8041725: Nimbus JList selection colors persist across L&F changes

[Anton Litvinov]

Hello,

Could you please review the following fix for the bug.

Bug: https://bugs.openjdk.java.net/browse/JDK-8041725
Webrev: http://cr.openjdk.java.net/~alitvinov/8041725/jdk9/webrev.00

The bug consists in the fact that Nimbus L&F sets "selectionForeground" 
and "selectionBackground" colors of "javax.swing.JList" component to the 
colors which are not instances of "javax.swing.plaf.UIResource" 
interface, what makes these colors persist after change to other L&F.

The fix removes "uiResource="false"" attributes from the tags in the 
file "jdk/src/share/classes/javax/swing/plaf/nimbus/skin.laf" which 
declare the selection colors for various styles of "JList" component. 
This change lets these colors become instances of 
"javax.swing.plaf.nimbus.DerivedColor.UIResource" implementing 
"UIResource" interface.

Thank you,
Anton
