JDG 7.1 image is built using jboss-datagrid-7.1.2-server.zip (https://github.com/jboss-container-images/jboss-datagrid-7-image/blob/datagrid71-dev/image.yaml). This file is not generally released for public consumption. We should be using the patch update method just like generally available releases of the Datagrid product.
