The problem: The testcase is in /share/esc/1-9895956/ you can reproduced it with jdk 1.4.2_5 or later with patch 109147-34. You will see the color problem. The problem looks like a "color flashing" problem. But it is not. The problem happens on all graphics cards, if you set it to 8 bit only. With 1.4.2_2 or older, you do not see this problem. Without 109147-34, even with 1.4.2_7 you do not see this problem either. To run the testcase: setenv JDKHOME /net/koori.sfbay/onestop/jdk/1.4.2_08/latest/binaries/solaris-sparc/bin 1. compile java program $JDKHOME/javac colorProblem.java 2. run the program $JDKHOME/java colorProblem 3. move mouse focus to app, then move away, you will see it. testcase: import javax.swing.*; import java.awt.*; import java.awt.event.*; class colorProblem extends JFrame { private static colorProblem fMaster = null; private static boolean toggle = true; public colorProblem(boolean master) {init(master);} private void init(boolean master) { System.out.println("in init"); //JFrame f = new JFrame(); setBounds(100, 100, 300, 200); if(master) setTitle("Master"); else setTitle("Slave"); Container content = getContentPane(); JButton button = new JButton(); button.setLabel("Exit"); button.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent event) { toggle = !toggle; System.out.println("button press:"+toggle); System.exit(0); } }); content.add(button); setVisible(true); } public static void main(String[] args) { System.out.println("in main"); fMaster = new colorProblem(true); } }
