Install Oracle Java 8

remove read access for ‘other’

Per default, every user may read the content of other user’s home directories. To change that to a more private setup, remove all rights for other from all user’s home directories: This needs only to be done to the parent directory (/home/[user]), no chmod -R is necessary.
