Name: jbT81659			Date: 08/27/2003

Locale: Windows, Solaris, (Linux not tested)
Regression: NO
Build: b16
This bug affects all test cases. The problem is specific only to jdk1.5.0-b16 not earlier builds. The Metal LookAndFeel imposes a light blue color over compnents custom colors set by the pogrammer inside applications and applets. 
Component color is overrided with the Metal LAF blue color. For example, picking a color from JColorChooser and applying it to a JButton will not have any effect, the JButton will still have the blue color from the Metal LAF.

Testcase:

Run the following code (jLayeredPane.java) with these commands for Motif and Metal LAF's

java -Dswing.defaultlaf=com.sun.java.swing.plaf.motif.MotifLookAndFeel jLayeredPane
java -Dswing.defaultlaf=javax.swing.plaf.metal.MetalLookAndFeel jLayeredPane

1. Under Motif each button is displayed with its set color(red, gray, white)
2. Under Metal all buttons are displayed with the LAF color (blue)

CAP member reported the same problem:

J2SE Version (please include all output from java -version flag):
  java version "1.5.0-beta"
  Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-beta-b26)
  Java HotSpot(TM) Client VM (build 1.5.0-beta-b26, mixed mode)

Does this problem occur on J2SE 1.4 or 1.4.1 or 1.4.2?  Yes / No (pick one)
  No

Operating System Configuration Information (be specific):
  SuSE Linux 8.2

Hardware Configuration Information (be specific):
  Intel PC x586

Bug Description:
  setting the color of a JButton like this
         jb.setBackground(Color.red);
  does work in 1.4.2, but not in 1.5.0
  (background: I use an application with colored buttons)

Steps to Reproduce (be specific):
  1. compile the enclosed code with J2SE 1.4.2 and
     run the program. The button is red
  2. do the same with J2SE 1.5.0
     button color is unchanged

Test program:

public class ColorButtonTest extends JFrame{
     public ColorButtonTest() {
         JFrame jf = new JFrame("ColorButtonTest");

                         + " for self-destruction...");
         // the following line has effect in J2SE 1.4.2, but not in 1.5.0
         jb.setBackground(Color.red);

         jf.getContentPane().add(jb);

same problem reported by another CAP member:

Bug Description:
  The bug was found testing the 1.5 release.  The problem is that the JButton's
  setBackground() method does not work.  To extend JButton and
  overrides the setBackground() method, the first call in that method is 
  super.setBackground(color).  The setForeground() method seems to work fine.
