Here is a part of the test's source (file: javax/swing/JApplet/4707289/bug4707289.java)
-----
    31      public void start() {
    32          try {
    33              robot = new Robot();
    34              SwingUtilities.invokeLater(new Runnable() {
    35                      public void run() {
    36                          try {
    37                              robot.keyPress(KeyEvent.VK_TAB);
    38                              robot.keyRelease(KeyEvent.VK_TAB);
-----
The test tries to press/release the TAB key programmatically.
The problem is that JApplet.start() method could be called when applet is not yet shown in the 
browser/appletviewer, so the applet does not receive appropriate events and the test fails.

How to reproduce:
=================
1. Run the following script on RH Linux 8.0 (you may need to change its variables)
2. Wait for a while after the applet with a "Test" buttor appears on the screen,
then close the appletviewer's window.
 
--- script start ---

--- script end ---

EVALUATION Name: apR10133 Date: 10/31/2002 Although this test passes over jtreg it fails if it run in appletviewer or browsers. The problem is that TAB is pressed/released at improper time. ###@###.### ====================================================================== The bug has been mistakenly marked as fixed in Mantis though actual fix is in Tiger workspace.
