      Description

      FULL PRODUCT VERSION :
      java version "1.8.0_20"
      Java(TM) SE Runtime Environment (build 1.8.0_20-b26)
      Java HotSpot(TM) 64-Bit Server VM (build 25.20-b23, mixed mode)

      ADDITIONAL OS VERSION INFORMATION :
      Microsoft Windows [Version 6.1.7601]

      A DESCRIPTION OF THE PROBLEM :
      When using the Nimbus look & feel, the selected item in a JList is not marked in the list's (default) selection foreground/background colors.
      By default, the selection foreground and background colors of a JList in Nimbus should be #FFFFFF (white) and #39698A (a dark blue), respectively. However, the text color of the selected item does not change (i.e. remains black), and it is marked in #D6D9DF (a light grey).

      REGRESSION. Last worked in version 8u11

      ADDITIONAL REGRESSION INFORMATION:
      java version "1.8.0_11"
      Java(TM) SE Runtime Environment (build 1.8.0_11-b12)
      Java HotSpot(TM) 64-Bit Server VM (build 25.11-b03, mixed mode)

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Set the NimbusLookAndFeel for your application, and make a JList visible on the screen (containing some items). Select any item.

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      The selected item is marked in the selection background color of the JList. Its text is shown in the selection foreground color of the JList.
      ACTUAL -
      The selected item is marked in some other color. Its text is shown in the default text color.

      REPRODUCIBILITY :
      This bug can be reproduced always.

      ---------- BEGIN SOURCE ----------
      import java.time.Month;

      import javax.swing.JDialog;
      import javax.swing.JList;
      import javax.swing.UIManager;
      import javax.swing.UnsupportedLookAndFeelException;
      import javax.swing.plaf.nimbus.NimbusLookAndFeel;

      public class SelectionBackgroundTestApplication
      {
          
          public static void main( String[] args )
          {
              try
              {
                  UIManager.setLookAndFeel( new NimbusLookAndFeel() );
              }
              catch ( UnsupportedLookAndFeelException e )
              {
                  e.printStackTrace();
                  return;
              }
              
              JDialog dlg = new JDialog();
              dlg.setDefaultCloseOperation( JDialog.DISPOSE_ON_CLOSE );
              
              JList<Month> comp = new JList<>( Month.values() );
              System.out.println( "Expected selection foreground color: #" + Integer.toHexString( comp.getSelectionForeground().getRGB() ) );
              System.out.println( "Expected selection background color: #" + Integer.toHexString( comp.getSelectionBackground().getRGB() ) );
              
              dlg.getContentPane().add( comp );
              dlg.pack();
              dlg.setVisible( true );
          }
          
      }

      ---------- END SOURCE ----------

      CUSTOMER SUBMITTED WORKAROUND :
      Setting the selection foreground and background colors of the JList to copies of the original selection foreground and background colors, respectively, fixes the problem:

              comp.setSelectionForeground( new java.awt.Color( comp.getSelectionForeground().getRGB() ) );
              comp.setSelectionBackground( new java.awt.Color( comp.getSelectionBackground().getRGB() ) );
