FULL PRODUCT VERSION :
java version "1.6.0_22"
Java(TM) SE Runtime Environment (build 1.6.0_22-b04)
Java HotSpot(TM) Client VM (build 17.1-b03, mixed mode, sharing)
ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [versie 6.1.7600]
EXTRA RELEVANT SYSTEM CONFIGURATION :
IE version 8.0.7600.16385
A DESCRIPTION OF THE PROBLEM :
Applet with JLabel with html text, like new JLabel("<html>foobar")
The first time the applet is run, the text shows ok.
The second time the applet is run while the plugin is still loaded in the browser, the HTML text is not shown.
This happens after a refresh of the page, but also when returning to the page after visiting another one.
Clearing the class loader cache does not fix the problem.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
I have put a test applet online.
Using IE8, surf to http://beta.rummigame.com/testapplet.html
When the applet is showing, press F5
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The same output as before the reftesh: two lines like:
A label with plain text
A label with styled text
ACTUAL -
Only the plain text is shown; the label with html is not
ERROR MESSAGES/STACK TRACES THAT OCCUR :
Probably related: when doing setText("<html>...") in a JEditorPane with a HTMLEditorKit, I get when the applet is started for the second time:
Error: java.lang.NullPointerException

REPRODUCIBILITY :
This bug can be reproduced always.
---------- BEGIN SOURCE ----------
package test;
import javax.swing.BoxLayout;
import javax.swing.JApplet;
import javax.swing.JLabel;
import javax.swing.SwingUtilities;
public class TestApplet extends JApplet
{
private void createGui()
{
setLayout(new BoxLayout(getContentPane(),BoxLayout.Y_AXIS));
add(new JLabel("A label with plain text"));
add(new JLabel("<html>A <u>label</u> with <i>styled</i> text"));

@Override
public void init()

createGui();
}
});
}
}
---------- END SOURCE ----------
CUSTOMER SUBMITTED WORKAROUND :
Close the browser or wait until the plugin is unloaded.
The applet runs fine all the time in Firefox (but my users mostly use IE and experience the problem when they restart my game applet).
