I am running Lucid and have the OpenJDK installed but not the Sun JDK. I was getting the problem of not being able to update Eclipse. I now use a launch script of:
#! /bin/sh
export GDK_NATIVE_WINDOWS=1 $HOME/eclipse-x86_64/eclipse -vmargs -Djava.net.preferIPv4Stack=true
and updates work fine. so this would seem to confirm that the issue is as hypothesized.
