216091 - hang if window closed with javascript self.close() when the page has a java applet

Status: VERIFIED WORKSFORME

(Core :: DOM: Core & HTML, defect)

Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.4) Gecko/20030624

When a window uses javascript to close, and it contains a java applet, it usually hangs the browser.  Clicking on links doesn't work.  Javascript will still open new browser windows, but the pages never load.  Typing an address into the location bar causes the browser to start the page loading cycle, but the throbber freezes and nothing ever loads.  When closing the browser, the application remains in memory and must be killed.  I replicated this with Firebird 0.6, Mozilla 1.4, and Netscape 7.1

Reproducible: Always

Steps to Reproduce:
1. Open the included test.html page.
3. Click the link to open java.html.
4. Soon after the java.html starts displaying click the close button.

Actual Results:  
If you click the close button the right ammount of time (about 1 sec on my machine) after java.html displays, the browser will be in the state described above where navigation doesn't work and the browser must be killed.

Reassigning to DOM Level 0, but this could also be OJI, I don't know.
But it is unlikely to be due to a bug in JavaScript Engine.

cenise: what happens if you open Tools > Web Development > Java Console
before you try your testcase. Do you see it fill with lots of messages
while the browser is hanging?

If not, do you see any errors in the JavaScript Console?

Sorry I assigned it to the wrong component; this is my first bug report.

It doesn't show any errors in the java console or the javascript debugger.

Attachment: This is the html source.

<INPUT onClick="javascript:window.close()" TYPE="BUTTON" VALUE="Close"
TITLE="Click here to close window" NAME="CloseWindow" >

The error is produced at this point

It's a thread issue. Workaround: use a separate javascript thread to close window
ie. 
timeout = setTimeout(closeme,100)
function closeme() {
  clearTimeout(timeout);
  window.close();
}
