647782 - Java not running on FF4 unless set to open in 32-bit

Status: RESOLVED WONTFIX

(Core Graveyard :: Plug-ins, defect)

Description

[arild.b.anda]

User-Agent:       Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:2.0) Gecko/20100101 Firefox/4.0
Build Identifier: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:2.0) Gecko/20100101 Firefox/4.0

Error message when loading Java-applet that this is not installed. Java is correctly installed however, runs as expected with Safari. Will only run with FF4 if started in 32-bit mode.

Reproducible: Always

Steps to Reproduce:
1.Asking web page to run script
2.Error message that plug in is missing
3.Clicking "Install"
Actual Results:  
Plug in not found (it is in fact installed)

Expected Results:  
Applet should start since Java is in fact installed already

There is no message to start FF in 32 bit mode and that this will fix the problem. I found out that myself (been prompted to change mode when encountering a different issue).

We need to be able to reproduce this bug to understand it.

There currently isn't enough information here to allow us to reproduce
it.

Please provide a link to a testcase (one that's accessible to the
general public) that demonstrates the problem.

Do you see this problem with any Java applet (for example the one at
the following URL)?

http://java.sun.com/applets/jdk/1.4/demo/applets/Clock/example1.html

Are you quite sure that what you're having trouble with is a Java
applet, and not some other kind of plugin?

Finally, your user-agent string (from comment #0) says that you're testing on OS X 10.6.  But are you actually testing on a developer preview of OS X Lion (10.7)?  It's a known bug that Java doesn't work in Firefox 4 on Lion (bug 645556).

Hello, no I am running 10.6.7 and FF4.0
I have now tried a variety of Java scripts (no doubt it is Java) and it boils down to one specific applet that will not work unless you start FF in 32-bit mode. The domain belongs to a bank, www.dnbnor.no and is restricted. You could try to send an email to [e-mail]
I called them on [phone] and they could confirm the situation is exactly as described above. They suspect it is the encryption that will not work with FF4/64 bit.
Please let me know what information you need if it cannot be retrieved from [e-mail], and I will try to relay it/put you in contact with a developer from their staff.

Thanks for the information.

JavaScript is *not* Java.  But, for the time being, I'll take your
word for it that what you're having problems with is a Java applet.

Give them the URL for this bug and ask them to ask one of their
developers to comment here.  He/she will need to provide a testcase
for this bug.  If it all possible it should be publicly accessible.
At the very least it must not require that I have an account at the
bank :-)
