      Description

      Lifecycle#canRewriteHudsonWar assumes in-place replacement of the war, while UpdateCenter#download actually writes to a temporary file first to prevent breaking the file if an error occurs. This can lead to the following exception:

      hudson.util.IOException2: Failed to download from http://updates.jenkins-ci.org/download/war/1.570/jenkins.war (redirected to: http://jenkins.mirror.isppower.de/war/1.570/jenkins.war)
