Motivation:
We should explicit specify the java version to use to ensure docker will rebuild the image once a new java version was released and we specify it. Also we should use openjdk for testing when possible.
Modifications:
- Explicit specify the java versions to use
- Use openjdk when possible.
Result:
Ensure latest java versions are used during testing
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.
