title: Java JRE Updating issue with CentOS
body: <p>I have just recently installed CentOS on my little server box. I am in the process of transferring my servers from Windows Server to Linux/CentOS, and I'm running into a small problem. </p>
  
  <p>I checked "Install java" when I was installing CentOS because I thought it would speed up the process. However, it installed Java 7, and I need to use Java 8 because our code uses a bunch of new features in Java 8.</p>
  
  <p>I have tried removing Java JRE 7 manually, downloading an rpm, and using <code>yum</code>. However, it seems that Java 7 is still installed, or is overriding the Java JRE 8 install.</p>
  
  <p>I can provide any logs neccessary. Thank you!</p>
