Comment 22 for bug 530414

I'm pleased to say that I've worked around this issue solely by fixing the "sat4j" problem as reported here:

https://bugs.launchpad.net/ubuntu/+source/eclipse/+bug/566131/comments/3

(execute the two "sudo ln" commands)

afterwards, I did this:

eclipse -clean -initialize
rm -rf ~/.eclipse

I was then able to proceed with a software update. No more "bundle" problem, no more 503's, no more failure to access download.eclipse.org, etc.

I did not have to change my JDK, or use "-vmargs -Djava.net.preferIPv4Stack=true" on the command line, or use a special environment variable. It just worked, on my vanilla Lucid Beta install updated yesterday.
