141825 - Sometime, not all the applets shown on the page.

Status: VERIFIED WORKSFORME

(Core Graveyard :: Java: OJI, defect)

Description

[Gottfried Ganßauge]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; de-AT; rv:1.0rc1)
Gecko/20020417
BuildID:    2002041711

When first visiting the URL mentioned above the applets load without a flaw.
When hitting the reload button, the browser freezes.
The applet loaded doesn't matter, as demonstrated by the URL
http://www.ep.haufe.de/~ganssaug/testApplet/testNoApplet.html. In this case
there is not even an applet loaded, because the class file doesn't exists.
The bugs seems to be triggered by the number of applet tags in the page:
http://www.ep.haufe.de/~ganssaug/testApplet/testApplet2.html only has two applet
tags and the bug doesn't appear.
In Internet-Explorer with the same Java-Plugin the bug does not appear.

Reproducible: Always
Steps to Reproduce:
1. Visit http://www.ep.haufe.de/~ganssaug/testApplet/testApplet.html
2. Watch the Java console initializing the four applet instances
3. Hit the reload button
4. Mozilla freezes

Actual Results:  Mozilla freezes

Expected Results:  Mozilla should reinitialize all applet instances again.

The Version of the Java Plugin is
Java(TM) Plug-in: Version 1.3.1_03
The bug also appears on the english version of the same mozilla build

WFM Win2k 2002050204 JRE 1.4
The reload is a bit slow / CPU intensive, but mozilla continues to work fine.

JRE1.3.1 is still the proposed Version to install.
The bug still appears with 1.3.1_03 on build 2002050206

I can confirm the behavior of the Applet-Bug reported by Mr. Ganßauge.
Additional I have testet the Applet-Bug with 2 Frames and 2 Applet-Tags per
Frame and this also causes Mozilla to hang. Thus the Applet-Bug occurs if there
are more than 3 Applet-Tags in a Page and even if the Applets can not be loaded.
My testing environment is Win2000/pro, Mozilla-Build-2002041711 and Sun's JVM
1.3.1_02.

I would like to confirm that I have also observed this bug during work on a 
dynamic page 
which contains a variable number of applets. With one or two applets, the page 
loads fine, but with more than two the browser hangs up completely. I am using 
Mozilla 1.0 RC2 under Windows 2000. The page that I am working on is:
http://dream.sims.berkeley.edu:9090/newshound/ip3/multi_graph.jsp
 Please note that this page (although work in progress, dog slow, etc.) works 
fine in Netscape 4.7, IE5, and Opera 5. In Netscape 6.2 the behavior is as 
reported for Mozilla.

The bug still appears with RC2 (2002051006)

Comment 6

[Joe Chou]

Tried the test case with moz1.0 rc2 (downloaded with JRE1.4 installed) on
Windows XP, and it seemed working OK. No hung after clicking the Reload button.

Reporter, when you downloaded moz1.0 rc2, did you also get JRE1.4 (should be
bundled and installed automatically)?

Comment 7

[Gottfried Ganßauge]

I didn't download an installer version.
The release I installed came from www.kairo.at as a zip archive which I just
unpacked into some directory to install it.
It uses my existing JRE_1.3.1_03; JRE_1.4.0 is not an option to date 'cause it 
has a bug in the URLConnection class which makes my app freeze under 
circumstances not yet fully clear.

Win2k SP3, Mozilla 1.2.1, JRE 1.4.1_01
The bug now has a different appearance:
Most of the time it works indeed but at times only three of the applets get 
reloaded.
