EXTRA RELEVANT SYSTEM CONFIGURATION :
Internet Explorer 7, 8, 9.
A DESCRIPTION OF THE PROBLEM :
When creating an applet dynamically in Internet Explorer (e.g. by Javascript in an html page) by using the <applet> tag the 1st time the applet is loaded the applet and browser are working fine. If one reloads this page and loads the applet a 2nd time the browser or Java Plugin freezes. The only solution in this case is to kill the browser process.
This behavior only depends on the usage of the applet html tag. If you use e.g <object> the browser / plugin will not freeze.
REGRESSION. Last worked in version 7
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. ) Load html page wich dynamically creates an applet
2.) 1st time the applet is loaded successfully
3.) Press F5 in Internet Explorer to reload the page
4.) Load the applet a 2nd time
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Java Applet is loaded correctly and is ready to work with.
ACTUAL -
Browser / Java Plugin freezes.
ERROR MESSAGES/STACK TRACES THAT OCCUR :
basic: Applet initialized
basic: Starting applet
basic: completed perf rollup
basic: Applet made visible
basic: Applet started
basic: Told clients applet is started
basic: Starting applet teardown
basic: Finished applet teardown
basic: Fortschritts-Listener entfernt: sun.plugin.util.ProgressMonitorAdapter@1bdbf51

REPRODUCIBILITY :

---------- BEGIN SOURCE ----------
Compile this small class
import java.applet.Applet;
import java.awt.Graphics;
public class HelloWorldApplet extends Applet
{
public void paint( Graphics graphic )
{
graphic.drawString( "Hello World!", 50, 25 );
}
}
Then use this html page in IE. To load the applet press the button "Create Applet".
<!DOCTYPE html>
<html>
<head>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script type="text/javascript">
$(document).ready(function () {
$('#button').click(function () {
$.ajax({
url: './applet.html',
success: function(data) {
$('#cave').html(data);
}
});
});
});
</script>
</head>
<body>
<button id="button" type="button">Create Applet</button>
<div id="cave" width="220" height="120">
</div>
</body>
</html>
---------- END SOURCE ----------
CUSTOMER SUBMITTED WORKAROUND :
1.) Do not install Java 7 update 4+
2.) Do use <object> Tag instead of <applet>
