I am leading the development of a new project. This project
has receintly bought 10 new Sun Ultra 10s running Solaris 2.6.
We are developing an application and really hoped to develop it
in Java using Swing. The java version we have installed is :
Solaris VM (build Solaris_JDK_1.2_01_dev05_fcsK, native threads, sunwjit)

We have created a very simple test application and find it
doesn't perform well if we our not running on our local
machine. For example: I am sitting at my local machine
(call it X) and telnet (or rlogin) to a remote machine
(call it Y). I type 'xhost + Y' on X and type 'setenv DISPLAY
X:0.0' in my telnet window to Y. When I run my Java
application that has a couple of buttons all implemented
in SWING, it doesn't run well. The window takes several
seconds to come up, resizing the window takes several seconds,
nothing is very responsive. Here is the application code:

import java.awt.*;
import javax.swing.*;

public class TestFrame extends JFrame {
  public TestFrame() {
    setSize(500,500);
    setBackground(Color.green);
    try {
      UIManager.setLookAndFeel("Metal");
    }
    catch(Exception e) {
    }
    JPanel topPanel = new JPanel();
    topPanel.setLayout(new GridLayout(3, 2));
    getContentPane().add(topPanel);
    topPanel.setBackground(Color.red);
    topPanel.add(new JButton("Yippee"), BorderLayout.NORTH);
    topPanel.add(new JButton("Skippy"), BorderLayout.EAST);
    topPanel.add(new JButton("YaHoo"), BorderLayout.SOUTH);
    topPanel.add(new JButton("Wow"), BorderLayout.WEST);
    topPanel.add(new JButton("Big Deal"), BorderLayout.CENTER);
  }
  public static void main(String args[]) {
    TestFrame mainFrame = new TestFrame();
    mainFrame.setVisible(true);
  }
}

I have searched the JDC, the Bug Parade, and the FAQs and have
not found any references to this problem. Could you please
tell me if this is a currently limitation of using light weight
components, or if there is a patch or workaround that I am not
aware of? If there is not a fix to this problem, how important
is it to the Java Team to fix this performance issue?

SAP can't upgrade their SAP Java GUI from JDK 1.1.8 to 1.2.2_05a or JDK 1.3
(checked Solaris b16) since customers with X11 remote display technolgy will not
be able to use it anymore.

The proposed workaround is not acceptable for SAP.
Their product uses components from third parties which use the baox layout.
A fix is needed
