Heroku buildpack: Oracle JDK

This is a Heroku buildpack for Java applications that use Maven as build tool. The buildpack installs Oracle JDK 1.8.0_111 and Maven 3.3.9 by default. The buildpack can also be configured to install JCE Unlimited Strength policy files and Ruby gems. If the application has NewRelic plugin installed, the buildpack will install NewRelic java agent automatically and enable it.
