515873 - launching the evj program now kills SeaMonkey

Status: RESOLVED DUPLICATE of bug 512834

(SeaMonkey :: General, defect)

Description

[Tom Schneider]

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X; en-US; rv:1.8.1.23) Gecko/20090823 SeaMonkey/1.1.18
Build Identifier: Mozilla/5.0 (Macintosh; U; Intel Mac OS X; en-US; rv:1.8.1.23) Gecko/20090823 SeaMonkey/1.1.18

The Evj program is an important program I wrote, described at:
http://alum.mit.edu/www/toms/papers/ev

Reproducible: Always

Steps to Reproduce:
1. click on the url given
2. java launches
3. Seamonkey crashes (window disappears)

Alternatively:
1. go to http://alum.mit.edu/www/toms/papers/ev
2. click on "Click Here to Start the Evolution!"
3. Seamonkey crashes (window disappears)
Actual Results:  
SeaMonkey crashes now.

Expected Results:  
I expect it to run the program.

I recently switched to Mac OSX 10.6 and this is likely to
be related to the problem.  The java code has worked fine many times
on SeaMonkey and earlier OS versions.

This is a very very important program for me, so fixing it is important.

The downloaded program runs fine.  Download from
http://www.ccrnp.ncifcrf.gov/~toms/papers/ev/evj/evjava.zip
unzip.  Open the directory and click on Evj.class to launch it.
Click 'Run' to have fun watching the evolution.
So it's got something to do with the way the program is launched.

I tried the problem file
http://www.ccrnp.ncifcrf.gov/~toms/papers/ev/evj/evjava/index.html
with Safari Version 4.0.3 (6531.9) on OS X 10.6 and it ran fine.
So the problem is specific to SeaMonkey.

Even more surprising, the web page opens the java just fine with Firefox:

Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.1.2) Gecko/20090729 Firefox/3.5.2

Can you try with Firefox 2? This uses the same Gecko version as Seamonkey 1.1
http://releases.mozilla.org/pub/mozilla.org/firefox/releases/latest-2.0/

Also, which version of Java is reported in about:plugins?

I downloaded Firefox 2.0.0.20 english US version ... killed by the page.

Java Embedding Plugin 0.9.6.4

Thanks for looking at this!

I see from the link on that page that
http://javaplugin.sourceforge.net/
says
The current version (0.9.7.2) of the Java Embedding Plugin
but that it's bundled with the browsers:

"The Java Embedding Plugin has for the last few years been bundled with current Mac distributions of all the Mozilla.org browsers -- Firefox, Seamonkey and Camino. So if you're using one of these browsers, you don't need to install the Java Embedding Plugin. But you may wish to replace the bundled version of the Java Embedding Plugin with a more recent version."

So it's not clear to me that I should upgrade.

See bug 494246, bug 493629 and bug 496187 for further info. Looks like manually updating the JEP plugin will fix your crash. You will probably have to take care when updating Seamonkey. A stack would help narrow down the precise cause, do you get the crash reporter come up? Are there any relevant entries in about:crashes?

I'm not familiar with Java on Mac so I'm can't resolve this.

I upgraded my JEP plugin from
http://sourceforge.net/projects/javaplugin/
and my program now work perfectly.  Thanks!
I hope this can become a standard part of the SeaMonkey browser.

The problem with the plugin is that the newer version only works with 10.4 and higher.
