Hi Ed. > Another potential cause is that the download.eclipse.org server will continue to serve old cache versions of files that are actually updated in the file system. So, it's possible that one updates a repository in the file system, and then a client might see a newer version of the compositeContent.jar/content.jar but an older version of the compositeArtifacts.jar/artifacts.jar.
