I tried to install swt 4.2 on my x86 netbook. I had only set up my own amd64 machine as a mirror, so portage tried to download from upstream. It got a 404 from eclipse.org. So I went there to d/l the file manually. It turned out that the path in the ebuild is wrong: MY_DMF="http://download.eclipse.org/...." should be MY_DMF="http://archive.eclipse.org/...." I didn't look into other java packages, but this problem might exist in other places as well. Reproducible: Always Actual Results: Archive download from upstream fails with 404.
