      FilePath.installIfNecessaryFrom, used from ZipExtractionInstaller, is designed to log a warning but continue in case the tool is already unpacked and the server returns an error while it is checking for a newer archive. Yet this stack trace suggests that this logic is not working, because the IOException comes after connect in getInputStream:
