At Heimdal Security, we have decided not to patch Java 7 to Java 8 or Java 6 to Java 7, because some of our clients prefer to use an older version of Java which is kept up to date.
If you have Java 7 and you want to use the latest version of Java, you must uninstall Java 7 from your computer and install the last version of Java from the official website: http://java.com/en/download/
