Motivation: The first EA builds for Java12 are released so we should allow to run with these in our docker-compose setup. Modifications: Add docker-compose configs for Java12. Result: Be able to run easily with Java12 as well.
Using the docker images
cd /path/to/netty/
centos 6 with java 8
docker-compose -f docker/docker-compose.yaml -f docker/docker-compose.centos-6.18.yaml run test
centos 7 with java 9
docker-compose -f docker/docker-compose.yaml -f docker/docker-compose.centos-7.19.yaml run test
etc, etc
