Comment 26 for bug 359407

I am using Jaunty 32-bit with Firefox 3.5 (3.5.7+nobinonly-0ubuntu0.9.04.1) from the Ubuntu Universe repository and OpenJDK/IcedTea (6b16-1.6.1-0jaunty1) from the OpenJDK PPA (https://launchpad.net/~openjdk/+archive/ppa). I have never had Sun JDK or GCJ installed on this system.

None of the Java applets I have tried work (for example, http://www.java.com/en/download/help/testvm.xml).

Prior to installing OpenJDK 1.6.x from the OpenJDK PPA (when I was using OpenJDK 1.4.x that came with the official Jaunty repositories) when I loaded a Java applet, Firefox would hang at 100% CPU and nothing but a grey box would appear in place of the applet. I would have to manually kill the Firefox process.

Now that I am using OpenJDK 1.6.x, Firefox does not hang upon attempting to load the applet, but still only shows the grey box. I can still do all other Firefox operations normally. I still get error messages on the terminal identical to those shown in this bug report. When I close Firefox, the Firefox process hangs, and I have to manually kill it before starting a new Firefox instance.

So from what I can see, the OpenJDK/IcedTea 1.6.x packages in the OpenJDK PPA do nothing for this bug except delay the hang until you attempt to close the Firefox instance. Can someone confirm whether simply adding the OpenJDK PPA and dist-upgrading to OpenJDK 1.6.x is enough to fix this? Do I have to do any extra voodoo like first remove and purge all of Firefox/OpenJDK/world? Do I have to manually delete any directories or symlinks? I have not done any manual mucking around with the Firefox or OpenJDK stuff, and was hoping that simply letting apt do the upgrade would be sufficient, but apparently it's not.
