From Bugzilla Helper:

BuildID:    2001080204

After installing the java plugin for linux, visiting any page containing java
locks up the client.  It does not ever appear to respond.

Reproducible: Always
Steps to Reproduce:
1. Download install 0.9.3
2. Go to http://java.sun.com/  Download Java Plugin for Linux.
3. Restart client (after getting rid of that xpicleanup stuff, of course)
4. Go to http://java.sun.com/

Actual Results:  Client locks up.

Expected Results:  Preferable:  Applets load
Acceptable: Applets fail fo load; Client responds gracefully.

* While I have not tried reinstalling the mozilla client itself, I have tried
downloading/installing/deleting applet and repeating the process. I have also
tried installing both from the website, and by downloading jre.xpi, installing
from local directory, as su.

* There was no relevant information in the console.  

* This is an SMP machine:

In my case it is happening with Netscape's default java plugin.

To clarify, mine was the default Netscape JVM, too.  I just went to
http://java.sun.com/ to get the "download plugin" trigger.

I'm not seeing this on recent trunk builds on RH 7.0.  Which Linux Dist are you 
using?
Using RH 7.1; Newest Ximian-Gnome.
I am using a highly customised Suse (6.3 I think) with a lot of Mandrake
packages and Enlightenment.

My machine is not SMP, it's a single AMD K6-3.

I can try and get a stack trace for java_vm if somebody can remind me how.

I see exactly the same behavior with 0.9.4 (rebuilt SRPM) on Red Hat 7.1 (rawhide
kernel 2.4.7-2) on a dual-PIII.
*** Bug 100030 has been marked as a duplicate of this bug. ***
When starting mozilla (0.9.4) from command line one message appears saying :
"LoadPlugin: failed to initialize shared library /usr/lib/mozilla/plugins/java2
[/usr/lib/mozilla/plugins/java2: cannot read file data: Is a directory]"

the plugins directory of mozilla contains the following :
- a directory : java2
- a link to usr/lib/mozilla/plugins/java2/plugin/i386/ns600/libjavaplugin_oji.so
- and libnullplugin.so

hope it can help.
If this helps (from top), you can see that after mozilla tries to load
www.javasoft.com, it has started a half a dozen java vms.

The plugin from an old version of the jdk,

[root@jade plugins]# /usr/java/jdk1.3.1/bin/java -version
java version "1.3.1-rc2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1-rc2-b23)
Java HotSpot(TM) Client VM (build 1.3.1-rc2-b23, mixed mode)

worked. The plugins from jskd1.4beta2 did not. Perhaps Sun changed something
important.

Hope that helps,

Dave

Me too (redhat 7.1, both mozilla 0.9.3 & 0.9.4) 

but since I use the famous

export LD_ASSUME_KERNEL=2.2.5

it works like a charm (using jre.xpi, sun jre or imb jre)(put "export blabla" 
on the top of the /usr/lib/mozilla shell script, just below the first line. It's
easyer..)

There is a known compatibility problem between recent version of mozilla, Sun
JRE 1.3 plugin the 2.4 kernel. For details, see:
http://bugzilla.mozilla.org/show_bug.cgi?id=84093 

Workaround: Upgrade your Java plugin (I suggest JRE 1.4) or set this enviornment
variable before starting mozilla:
export LD_ASSUME_KERNEL=2.2.5

Reporter: if above helps then please close this bug as dupe of 84093

Reassign to mtchan.

I am going to close this as dup of 84093 if there is no objection.
