Hi,
maybe I just had a similar problem, although without "missing library": With sun-java6-plugin instead of OpenJDK, firefox just freezes completely when loading the Facebook photo upload applet. The browser consumes 100% on one CPU core, and the process "java_vm" another 12 % on the second core. Killing java_vm crashes the browser.

Best regards,
Dieter

Pretty serious if it causes firefox to outright freeze.

Confirming here with firefox 3.5.8+build1+nobinonly-0ubuntu0.9.10.1

Working on my 32 bit machine, but not my 64-bit machine.

applet viewing is imporived in lucid. please could you recheck with ubuntu lucid and give examples/URLs for failing applets

Is there a ppa to test against karmic? I don't have a machine for lucid at the moment.

http://java.com/en/download/help/testvm.xml still locks up firefox in karmic for me.

No go for me on lucid 64-bit. Well, Firefox didn't lock up, but Java didn't work, either.

Here's what I did:

I visit http://java.com/en/download/installed.jsp, click Verifiy Java version, the animation circles for a bit, then goes to a page that says: "Sorry! We couldn't find the document requested." at URL http://java.com/en/download/installed.jsp_jre_version=1.6.0_18&vendor=Sun+Microsystems+Inc.&os=Linux&os_version=2.6.32-16-generic

I ran it from the terminal, and here's what came out during the attempt:

"No go for me on lucid 64-bit. Well, Firefox didn't lock up, but Java didn't work, either."

This is what I'm experiencing as well. Was hoping Lucid would fix this problem but it didn't. I decided to look for others having similar problems and this seems to be the closest so far. I was testing with:

http://dslr.net/speedtest?java=1

I've attached my .xsession-errors file.

Jason, when you said you ran from the command line, does that mean you downloaded the applet and ran it locally?
