I had the same problem on a hardy amd64 hardy dom0 running xen 3.2 and kernel 2.6.24-21-xen. When I tried to install sun-java6-jdk on an i386 lucid domU.
I can confirm that the xen patch mentioned by Stefan in comment 58 solved my problem. Before patching, the installation of sun-java6-bin crashed reliably, and calling 'dpkg --configure -a' showed this: ----- Setting up sun-java6-bin (6.21dlj-0ubuntu1~lucid1~ppa1) ... update-alternatives: using /usr/lib/jvm/java-6-sun/jre/bin/ControlPanel to provide /usr/bin/ControlPanel (ControlPanel) in auto mode. ... update-alternatives: using /usr/lib/jvm/java-6-sun/jre/lib/jexec to provide /usr/bin/jexec (jexec) in auto mode.
