Default Java plugin on icewasel - stopped working

This is probably a common question, but I couldn't find a solution by simple

I have a workstation running Debian/Squeeze, with sun java and iceweasel
installed (6-16-1), but no java applets seem to work. They did work some
weeks ago. I have updated my system a few times ion between, but now even the
simple one at
says "Error. Click for details".

When I click, I get a typical java backtrace (see end of this mail)

This tells me that java plugin, and java itself is installed and running
all right.

The first exception is
load: class JavaVersionDisplayApplet.class not found.
java.lang.ClassNotFoundException: JavaVersionDisplayApplet.class
and looking deeper in the stack, I see
Caused by: java.net.ConnectException: Network is unreachable

Now, obviously my network is reachable, since I get to the test page. Is
there some kind of security thing preventing the java plugin from loading the

it may be worth mentioning that this is on amd64, but I also have an older
i86 installation, into which I can schroot. There is an older iceweasel with
sun-java5-plugin 1.5.0-14-1etch1, which has started to fail the same way. I
don't think I have updated that schroot for a while.

Any ideas and suggestions would be helpful!
