      Description



      Name: nkR10003 Date: 10/23/2000



      JavaDoc comments for BasicListUI.uninstallDefaults states:
      " Set the JList properties that haven't been explicitly overridden to
      null." Actually JList properties such as (selection)background,
      (selection)foreground and font are not null after uninstallUI
      (uninstallDefaults) invocation.

      Example below demonstrates this problem:
      ------------------example--------------------
      //test.java
      import javax.swing.plaf.basic.*;
      import javax.swing.*;
      public class test {
          public static void main(String[] args) {
              BasicListUI ui = new BasicListUI();
              JList list = new JList();
              list.setUI(ui);
              ui.uninstallUI(list);
              
              if (!(list.getBackground() == null
                      && list.getSelectionBackground() == null
                      && list.getForeground() == null
                      && list.getSelectionForeground() == null
                      && list.getFont() == null)) {
                  System.out.println("background: " + list.getBackground());
                  System.out.println("foreground: " + list.getForeground());
                  System.out.println("selection background: " + list.getSelectionBackground());
                  System.out.println("selection foreground: " + list.getSelectionForeground());
                  System.out.println("font: " + list.getFont());
                  System.out.println("Test Failed");
                  System.out.println("===========");
                  System.exit(1);
              }
              
              System.out.println("Test passed OK");
              System.out.println("==============");
          }
      }
