To upgrade to the latest and greatest, just follow the instructions given below. First let’s download the goodness from Oracle, the JDK 8u51. Tricks needed with the cookie part stated as parameters since we’re downloading via wget.

sudo wget --no-cookies --no-check-certificate --header “Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie” “https://download.oracle.com/otn-pub/java/jdk/8u51-b16/jdk-8u51-linux-x64.rpm"
