Description

[Les Gasser]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.8) Gecko/20020207
BuildID:    2002020712

When viewing gbif.org page and clicking a button
that is a java applet, Mozilla immediately
crashes, and the talkback facility
doesn't come up. 

Reproducible: Always
Steps to Reproduce:
1. Point mozilla to "http://www.gbif.org/"

2. Click on the button at the left titled
 "About GBIF". I believe this is a Java applet.

3. Mozilla immediately crashes, and the talkback facility
doesn't come up. 


Actual Results:  Mozilla immediately crashed and the talkback facility did
not come up. 

Expected Results:  Open a new page as usual.

wfm using build 2002022808 on Linux + JRE 1.4.0-b92.

bug only shows on Linux. Java is involved. FrontPage generated page with
fphover.class.

Known sun's jdk 1.3 problem with fphover applet.

=> Dupe of 57372.

reporter: Please upgrade to jre 1.3.1 or 1.4 (1.4 is better).
(Latest 1.3.1 may also have no problem - please try appletviewer
 on testcase from bug 57372 to verify)

*** This bug has been marked as a duplicate of 57372 ***

Olivier, merci de ton message.  

I had actually been using the Java 1.3.1 plugin. 

With the Java(TM) Plug-in 1.4.0-b92 the www.gbif.org page does not
fully load and init the fphover.class applets - so I can't tell
whether clicking on them crashes mozilla in the same way. Rather than
displaying buttons, the gbif.org page now just displays broken applet
panels. See below for Java Console output. The current behavior
clearly isn't right.

I tried pointing at all the testcase URLs in bug #57372 and they
worked fine. I also tried many of the testcases in other bug reports
that were mentioned as duplicates of #57372, and the ones I tried also
seemed to work fine - i.e. fphover.class applet did not seem to be
causing problems in them. So it would seem something else is
happening with respect to the gbif.org page.

From the About Plugins window

Crash/hang here is known jre 1.3 problem. Updating the summary.

Reporter:
  Please try to open java console and set trace level to 5 before visiting the
page. 
Please post console output here.

Well, i am able to reproduce this. 
However, i am not quite sure it is really bug.

Applet is created with following 
    <applet code="fphover.class" codebase="../_fpclass/" width="140"
height="30">

But the URL of original document is 
  http://www.gbif.org/

Therefore plugin tries to load 
  http://www.gbif.org/../_fpclass/fphover.class
that is obviously missing.

The only thing that prevent me from closing this bug as INVALID 
is the fact applet was load with 1.3. However, i think this was because 
java plugin had normilized urls internally (and as sideeffect 
not balanced "../" was removed).
