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.
