Install Oracle Java on the Ubuntu base image.
docker build -t wmit/java .
This image is intended to be used to build other docker images that
require Oracle Java. If you want/need to run bash inside the container
you can use
docker run -i -t wmit/java /bin/bash
The java version can be adjusted by changing the Dockerfile in lots
of places (lines 6, 9, and 10) prior to building the image.
