SYNOPSIS
--------
appletviewer cannot show swing components
OPERATING SYSTEMS
-----------------
Redhat Enterprise Linux 6
Windows XP
FULL JDK VERSION
----------------
java version "1.7.0-ea"
Java(TM) SE Runtime Environment (build 1.7.0-ea-b132)
Java HotSpot(TM) Client VM (build 21.0-b03, mixed mode)
DESCRIPTION
-----------
This is not reproducible when the applet is run in the browser.
This is reproducible using appletviewer.
This looks very similar to CR 7002612, which was closed as a duplicate of CR 6986229. However, issue can reproduce this issue on 7-b132 despite the fix for 6986229 being delivered in b123.
Appletviewer cannot show its inner components just after starting. When I resize the appletviewer's window, I can see the inner components correctly. A similar AWT sample didn't have the problem.
Adding invalidate() at the end of the init() method in the testcase works around issue.

--- swing.java ---
import java.awt.*;
import javax.swing.*;
import java.applet.Applet;
public class swing extends JApplet {
public void init(){
Container c = this.getContentPane();
c.setLayout(new BorderLayout());
JScrollPane scrollPane = new JScrollPane();
scrollPane.getViewport().add(new JTextArea());
c.add("Center",scrollPane);
c.add("South",new JTextField());
// workaround
// invalidate () ;
}
}

REPRODUCTION INSTRUCTIONS
-------------------------
Compile the sample code and load html by appletviewer. Note that the appletviewer doesn't show inner components. It shows grey background.
WORKAROUND
----------
See testcase (add invalidate()).
