Status: RESOLVED FIXED

DOM Inspector shows no attributes for EMBED element on this page while Java
applet is running, and crashes if you move the highlight across the element too
many times. Confirmed clicking with mouse, not positive if using keyboard has
same effect or not. May actually be related to the number of times it attempts
to display attributes of EMBED element, not sure.

Reproducible: Always
Steps to Reproduce:
1.Open DOM Inspector via Tools menu
2.Enter the URL of the attached page
3.Click back and forth across the three children of BODY about half a dozen times
4.It goes boom!

Actual Results:  The entire browser crashed and made a talkback report

Expected Results:  Shown me the attributes of the EMBED element, and not crashed.

Talkback ID TB6034008E is from this exact test case that I will attach.

The following talkback IDs are from the same problem, either on the original
page, or test cases as I was trying to trim out the non-essentials.

TB6033630H
TB6033574H
TB6033035M
TB6032042G

Attachment: Test case HTML - needs Java class file too

Make sure you put this and Clock2.class in same directory before using test
case

Attachment: Test case Java file

This file needs to be in same directory as testcase.html for that to work.
Technically, any Java applet should work, as the original page this crash
occurred on was an internal applet, and after substituting this Clock2.class
from java.sun.com it still produced the crash though.

I didn't crash using build 2002050705 on Win2k (trunk) + JRE 1.4.0.
What Java version are you running ? Do you also crash using latest nightly build ?

About Java Plug-in says:

Java(TM) 2 Runtime Environment, Standard Edition 1.3.1
Default Virtual Machine Version 1.3.1-b24
Java(TM) Plug-in 1.3.1

The install file for the JRE was identified as version 1.3.1_01.

I have never used a nightly build, and would prefer to avoid risking installing
one on any of my machines next to the Mozilla milestone builds I normally use. I
noticed this bug when I installed RC1 on my work machine hoping to avoid
problems I have been having with IE lately. I certainly don't want to risk a
nightly build on this work machine, however. :)

Hopefully the fact that you aren't crashing just means it's already been fixed,
and I just couldn't find the matching bug.

I do not appear to be able to reproduce this bug on Mozilla 1.0 RC2 (Build ID:
2002051006)
