amd64 and sun-java6-jdk

["Tony Maher" <am50em@gmail.com>]

Hello,

I am trying to install java6 from etch backports on an amd64 machine.
Problem is that  sun-java6-jre (machine independent) is version 6-06-1~bpo40+1
(which is version  i386 uses) but the rest of amd64 sun-java5 packages are  6-00-2~bpo.1

apt-get -s install -f sun-java6-jre sun-java6-jdk sun-java6-doc sun-java6-demo sun-java6-bin

  E: Broken packages


Presumably jre version 6-06-1~bpo40+1 would be fine???
If so how to force the install?

thanks
